A list of puns related to "CNAME record"
I bought hosting at an external photography hosting site because of all the extra client gallery and billing perks built in that would take a lot of time to roll out on my own in a custom site or CMS.
However - I might, overtime, want to use AWS ML services for image pipelines and special image processing tools for customers (IE modernizing old photographs) - So I registered my domain on Route-53. I would eventually point subdomains at those service.
BUT - I can't just set the CNAME + A record to the external site. It just won't resolve. I'm not sure if there's something about hosted zones needing some sort of outbound rules, or if the NS pointers AWS assigns need to be set to something else. Or if there's some IAM policy I'm not even thinking about.
Any clues here? I've tried searching but no dice thus far.
So I have a CNAME record: login.example.com -> auth.com which works but our customer is requesting a TXT record for verification of DNS.
I don't know exactly what they're asking for and I'm not sure how I should go about doing this, anyone able to point to the right direction?
This seems like a basic question but I am a little confused. I have a vendor who needs an internal cname record created for one of our VM's (server1.domain.com). I created the cname record in DNS so now both hosts resolve to the same IP address when I perform an NSLOOKUP individually. However, the vendor is saying that when I do an NSLOOKUP by the IP address, both the server name and cname (alias) should resolve. But when I test it, I only get the server1.domain.com host name and not the alias on the cname record. Does this mean it is not set up properly or is there a better way to test this?
Hey r/PowerShell
I'm working on automating some of our failovers at my company and we do a lot of CNAME changes to swap between DC's. I'm having a hard time finding information on being able to do this with PowerShell on my DNS server. Is this something that can be done?
What I want is to take make existing Cname testcname@company.com -> server1@company.com to point to name testcname@company.com -> server2@company.com.
Hope this makes sense to someone lol
Hi, Let me preface by saying that Iβm a nocive at best when it comes to DNS. Iβm in the process of migrating my blog from AWS to Ghost (CMS provider) but having issues setting up the domain.
My blog isΒ https://packetswitch.co.uk and my DNS register is AWS Route 53. At the moment I have an βAβ record pointing to the AWS EC2 instance IP address and everything works okay. I'm thinking of moving my blog from EC2 to the CMS provider where I got to keep my domain name. They advised me to create a CNAME record pointing to their service as follows.
Record Type | Host | Value |
---|---|---|
CNAME | @ | packetswitch.ghost.io |
A (optional) | www | 178.128.137.126 |
I did the changes but my website was only accessible via www.packetswitch.co.uk and I couldn't resolve packetswitch.co.uk.
Any idea? Can someone clarify what does '@' sign means on the CNAME record?
I have my blog shared on multiple social media platforms so, I want to keep the root domain rather than using the www subdomain (www.packetswitch.co.uk)
Thanks in advance. Is there a way I can set up a record where all the queries to packetswitch.co.uk is forwarded to www.packetswitch.co.uk.

Thanks in advance.
So I purchased my domain through GoDaddy (www.mySite.com)At the same time, I purchased my custom email address with them (myName@mySite.com, uses Microsoft 365).Then upon creating and hosting my website through Create.com, my GoDaddy email broke as I changed my DNS provider/manager to be Create.com and not GoDaddy.
Now I am trying to point my DNS records through Create.comβs Cpanel back to what GoDaddy tells me.I found a procedure from GoDaddy to do this (I'd link to it, but you need to be logged in to see it).The procedure says, if your DNS is not managed by us, add these records to your account at the other company:
Here is what confuses me:
Any clarification you can provide on this is greatly appreciated. I obviously donβt have a firm grasp on how this all works yet (but I'm hoping to get there!).
Thanks!
Hello all,
I work for a small carrier and have been porting in customers from AT&T for several months now and have noticed a pattern of our new customer's CNAME not presenting what it previously did only when calling active AT&T customers.
I can call every other major carrier and the CNAME presented is what we have published(most cases identical to what they had on AT&T).
Anyone else experience this or find a solution?
All of the major search engines have Safe versions that intend to filter out adult content. They each recommend using a CNAME record to map their primary domains to the safesearch versions, so that if their ip address changes it won't break our access to their search engine.
However, I cannot find any instructions for how to implement this on Windows Server DNS.
Does anyone know how to force Safe search without setting it to a fixed IP?

I have a bunch of FQDNs which have A records that are updated by DDNS. Most of them are subdomains.
I'd like to set up cname records for the subdomains, and simplify my DDNS requests/configuration. Will that break my existing configuration, assuming that the FQDNs I've specified in my server blocks haven't changed?
Hello /r/sysadmin! - I have lurked here for SO many years but I believe this is my first post.
I have a subdomain with a CNAME setup. I need to add a TXT record for a verification with Google Cloud. While I understand this is technically not supported because of RFC1034 most NAMESERVER hosts seem to allow it. The issues is, I've come across an Infoblox server that does not allow this.
According to this link there is a way around it using --txt-prefix but I have no idea how to implement this. I've searched Google for --txt-prefix and I come across many posts saying it's the solution and that said flag exists but none that say how to apply said flag. I'm hoping someone can help me figure out how to make my needed TXT and CNAME live together in harmony...or at least look like they do when a DNS request is made.
Hi,
I have a major website with the following DNS records (modified for privacy)
@ A 98.131.41.232
www A 131.35.119.115
www CNAME contoso-cms-corp.trafficmanager.net
My website is working fine. The records have been in place for years. I've recently spoken to my support company about some DNS changes and they tell me that the "CNAME www" and "A www" should not co-exist for the same domain as it can cause issues, particularly with caching. Before I delete the www A record, I wanted to get a second opinion - could removing the "www A" record cause an issue (most traffic seems to be using the Azure traffic manager)?
Thank you,
Thank you, bluelink279 - his suggestion about Email Octopus was correct.
Thanks to everyone who tried to help me! All of you are amazing!
Hello everyone!
Today I found strange values in CNAME records in the DNS of my domain. They seem like keys for something and they all have the "***.argus.eoidentity.com" value.
To be honest I have no clue what those records belong to and I don't know who added them to my DNS zone. I tried to google "argus.eoidentity.com" (and similar combinations of "eoidentity" and "argus") and did not find any information about it and which application this may belong to. I also have the same value in the SPF, however, there are no IP addresses specify when I open that DNS-query (include:***.argus.eoidentity.com).
If someone had similar records in the DNS or knows what those CNAME records belong to, it will be much appreciated if you tell me! Right now I don't know whether I need to remove them or not....
Thank you!
Hello,
I have about 20 domains and one main domain.
Right now all my domains use an A record for 'cdn'.
I am thinking about changing this to a CNAME which points to an A record on my MAIN domain.
Example:
Main.com has an A record for cdn
Otherdomain.com has a CNAME record for cdn that points to cdn.main.com (20 domains setup like this)
Is there a SEO penality for doing this? All my sites are doing great and don't want to do anything to jeopardize it. Just trying to implement some anti DDOSing features.
Thank you!
Hi all,
I posted this on google support as well, but I am pretty desperate so I figured I'd post here as well! Summary of the issue (some screenshots in the above link as well):
I have a domain name I purchased through NameCheap, CharmCityYIMBY.org. For over three months I've been trying to set up a custom domain without success. I have spoken with NameCheap support, who say I've done everything correctly and recommend I reach out to Google, so here I am.
Troubleshooting so far:
From my google site, I go to Settings-->Custom Domains-->Start Setup-->Use a domain from a third party-->verify your ownership. I follow the instructions here (https://support.google.com/a/answer/6142985?hl=en) and waited minutes/hours/days without successfully verifying.
I further followed Namecheap's guidance here (https://www.namecheap.com/support/knowledgebase/article.aspx/9252/2208/how-do-i-add-my-domain-to-google-sites/), which also encourages setting up a CNAME and URL Redirect.
I also tried to follow the troubleshooting here (https://support.google.com/a/answer/2716888#zippy=%2Clook-up-txt-records-using-a-free-web-service), but it appears I'm able to successfully look up my TXT records, so I'm really not sure what I'm doing wrong.
Despite all this, I continue to fail verifying my domain. I'm at wits end and would love any guidance on how to resolve this--my only ask is that this is broadly beyond my technical know-how, so I'd very much appreciate layman's explanations for how to do things. NameCheap's tech support was not able to help me at all, and they said I was doing everything right.
Thank you in advance!!
Edit: OK so I went to this older post and the comment from /u/googlesitesexpert which took me to here. So somewhat bizarrely, I went to Google Search Console and attempted to verify my domain through that process instead of directly through google webmaster central (which is where google s
... keep reading on reddit β‘In response to the new DNSSEC launch for route 53, i went on a deep dive. So everyone knows you cannot use DNSSEC on a zone that uses an alias record that points to CloudFront (possibly all alias records but havenβt confirmed).
It got me thinking, is there any benefit to using an alias record over a CNAME? The one I can think of is when wanting to map your root domain to a resource and CNAMES arenβt usually support
I'm really confused. I've tried using dnslookup online, I've DiG in my linux terminal, etc. but it keeps returning no CNAME on that domain even though for fact they not only exist, they work. Problem definitely PEBCAK.
I know the existing CNAME records work because in Office365, the CNAME records that Microsoft desires me to add to our domain dns have been added and they're flagged as valid in Office365. One CNAME record that's been incorrectly input is flagged as invalid there. It stands to reason that therefore that one CNAME record works.
I'm asking because I added 2 more CNAME records as per microsoft's explanation for DKIM activation on my custom domain, but microsoft keeps telling me there's no CNAME records for this when I try to activate DKIM in the Office365 settings, and when I try to check myself for the CNAME record with dnslookup/dig, nothing returns.
Please explain to me like I'm 5 years old.
Records that Office365 wanted that are flagged as valid include
(CNAME) name: enterpriseregistration
value: enterpriseregistration.windows.net
and also one related to intune, enterpriseenrollment.
and the ones related to DKIM that I had added today would be:
(CNAME) name: selector1._domainkey.ourdomain.com
value: selector1-ourdomain-com._domainkey.ourmsname.onmicrosoft.com
and the same for selector2.
I can't publish our company's name, I am sorry, but what is it I should look for to get the CNAME record to show when I DiG for it or use some other dns lookup?
Thank you!
I'll be hosting a site for someone (on their subdomain) who can't make frequent changes to their DNS, but I want to be able to implement a failover mechanism where I can change the A record whenever I need to (or have a Cloudflare load balancer do it).
I registered a new domain I control and pointed its @ A record to my server's IP address. Then, I deleted the subdomain's A record and added a CNAME instead, pointing to my new domain. If the server goes down, Cloudflare's load balancer can now change the A record on my domain, and I won't need access to the subdomain.
Am I doing the right thing? I'm worried about making the wrong decision for this setup and I have never tried this particular method before.
ALIAS records have been a long time work around to using something other than an A record in the root/APEX of your domain.. While the documentation SEEMs to indicate that it is possible as far as I can tell all that is ACTUALLY supported is an A record ALAIS to a traffic manager which then MUST also contain A record endpoints.
In essence NO you can have a CNAME to an external resource in your APEX in a Azure zone? Am I correct?
This is done easily in other providers such as Cloudflair or Dyn and has been for years.. It is non-standard as far as DNS but common, it is also necessary when using certain DDOS solutions that only expose a CNAME.
TL;DR want to point [mydomain].com (apex/root) directly to a CNAME, already able to do this with Cloudflare or DYN but trying to determine if it is possible with Azure DNS.
Hi,
Just wondering if this is typical for website companies to do, and if there is any way around this besides giving them access to our DNS hosting login. Here is what they wrote: "We use Letβs Encrypt for our SSL certificates, we have a bunch of Amazon Web Hosting instances which each run PLESK which is a type of server management software which includes Letβs Encrypt. The problem in your particular case comes in the fact that our PLESK server doesnβt manage your DNS records".
I host my site on my home server and use a docker container that updated my dynamic IP to Route53 since I manage my records for my domain there and purchased my domain as well.
This gets updated to an A record called dns.domain.com.
So now I use my Nginx rever proxy at home with the proper forwarding in my home router to point the various subdomains to different docker applications. Just made a CNAME record point to the dns.domain.com with the subdomain of my choosing. Easy enough.
However my ghost blog site I just setup I wanted to setup 2 CNAME records for www and non-www same way but only my www record resolves. I use an asterisk for the non-www CNAME record as an @ symbol doesnβt seem to be supported.
But the problem is my non-www doesnβt resolve to my home IP. What can I do?
I offer my app to my clients using my own subdomain to host it.
Similarly to Shopify, when a new customer sets up his instance, this should be accessible through: customername.myappdomain.com
The app is hosted somewhere else and I need to create a different CNAME and a TXT for every instance.
How can handle hundreds of different CNAME and TXT records on the same domain?
Thanks so much in advance
I am configuring my Lightsail DNS zone via this guide. I bought the domain via Route 53 and made sure that the namservers there are the same as the nameservers from the Lightsail DNS zone.
Here is how my records are configured in the Lightsail DNS:
A record | Subdomain | Resolves to |
---|---|---|
@.mydomain.com | StaticIp |
CNAME record | Subdomain | Maps to |
---|---|---|
www.mydomain.com | mydomain.com |
Should the Maps to part of my CNAME record be @ instead of mydomain.com?
[SOLVED] So I'm trying to setup a ftp using my domain name. I am using an A record 'ddns.domain.com' that I dynamically update. I have also created a CNAME record 'ftp.domain.com', pointing to ddns.domain.com. However after looking at the IPs these two record redirect to, it seems that while ddns.domain.com is correctly redirecting at my IP (and so I can use that domain name to connect to my ftp), ftp.domain.com is redirecting at a completely different IP (and hence I cannot reach my FTP server using this domain). I thought a CNAME record would redirect to the same IP of the A record it's pointing to. Am I missing something ? I hope the question is clear enough. Thanks !
Edit : SOLVED. As guessed by u/BenjaminGordonT, I am using Cloudflare and the CNAME record was proxied by Cloudflare servers. Switching to 'DNS only' solved my issue. Thank you all for taking the time to answer !
So I have a CNAME record: login.example.com -> auth.com which works but our customer is requesting a TXT record for verification of DNS.
I don't know exactly what they're asking for and I'm not sure how I should go about doing this, anyone able to point to the right direction?
