I am being asked to create a CNAME pointing from autodiscover.mydomina.com to autodiscover.newdomain.com I am assuming in webmin you go to the Name Alias Link under the appropriate zone enter autodiscover under Name and under Real Name add: autodiscover.newdomain.com. Which then looks like: Name TTL Real Name autodiscover.mydomain.com. Default autodiscover.newdomain.com. Is that correct?

Why is that a CNAME, when they're different domains? Wouldn't you just put a separate A record in each domain pointing to the same IP?

You may be slightly confusing in your question. You will need to add the name autodiscover IN CNAME newdomain.com. but its unrelated to the current domain autodiscover.mydomina.com On 01/28/2010 02:36 PM, Vernon wrote: > > I don't know it's what they have requested. > > > > > > *From:* Stuart Biggerstaff [mailto:bi...@li...] > *Sent:* Thursday, January 28, 2010 3:49 PM > *To:* Webmin users list > *Subject:* Re: [webmin-l] Semi-urgent DNS Help Needed > > > > Why is that a CNAME, when they're different domains?

I'm not really sure what they are asking as typically I create my own A and MX records, however what I am assuming is that they want me to create a CNAME that points from my domain sever to theirs. It is basically an MX record for a web site I host for them. All email must go through their server. I would love to just create an A record that would point at their IP address but 1) I don't know how many IP addresses they are using and 2) I never know when they will change the IP address so creating a CNAME pointing at the A record makes sense to me I just don't know how to do it with WEBMIN.

So you don't have to update two records if the IP of the CNAME target changes. This is particularly useful if you're hosting many domains on a cluster; if for some reason you need/want to change the exposed IP of your cluster, you just update the IP on your main A records, and the CNAMEs for other domains' "mail.<domain>" records pointed to your own "mail.ipsdomain" address pick up the change without having to rewrite hundreds or thousands of DNS records. -kgd |

That's correct, but he is talking about 2 domains which both require A entries regardless of the IP. Then the autodiscover CNAME can be implemented for both.

An example is you have a Web server within a DMZ behind some sort of NAT scheme; let's say it's www.example.com on that outside and that resolves externally to a public address, but internally to a private address. Your internal network has hosts of the variety hostname.sitename.example.com. Now www.example.com on the inside is really webserver.sitename.example.com and your DNS server internally serves up sitename.example.com. Rather than going out the Net, your internal clients will want to to talk webserver.sitename.example.com, but you want to still access via the URL www.example.com, so you just set cname for for www.example.com pointing to webserver.sitename.example.com. Just an example I've seen in umpteen places. Clear as mud, right? |
