I just read this article:
http://support.algx.net/cst/dns/dns2.html
Basically it says that if I want to have 2 domain names pointing to 1 IP, I should do this:
A Record: onedomain.com -> IP
CNAME Record: twodomain.com -> onedomain.com
Instead of this:
A Record: onedomain.com -> IP
A Record: twodomain.com -> IP
... Is this true?
I've always used the 2nd way (2 A records), and it always worked, and besides, if you're going thru the CNAME, doesn't the user have to make 2 DNS calls instead of one?
Can someone clear up please?
Also, do we need CNAME records for anything other than this?
I guess something like
mom.domain.com -> dad.domain.com can't be accomplished via an A record, can it?
