CNAME www.example.com to example.com?

[primexx]

I currently have A records on both www.example.com and example.com pointing to the same IP. I just came across a site that CNAMEd the www. address to example.com and only had the A record in example.com itself. It seems like a pretty good idea, I can't think of anything that says you're not supposed to do that, but I just want to double check with you guys to make sure I'm not missing something obvious here. Can you CNAME the www. to the root domain (or is it a good idea)? Thanks!

Can't you just do an A Record like this :

* 86400 IN A xxx.xxx.xxx.xxx

to get everything pointing to your IP-Adress ?

I did some further research and it looks like the thing you want to achieve is impossible,

This one may explain this a little more.

You could workaround this with a 302-redirect, making www.example.com redirect to example.com

Yes, you can use a "www." CNAME record pointing to "example.com" and then have "example.com. IN A my.servers.ip.address". CNAME is just a alias, and can point to any A record in your zone. Ex. you can create CNAME records for "www.", "owa.", "smtp." that all point to the same A record("example.com") if you have all services that host.

This is pretty common practice, primexx.

@ IN A IPADDRESS

WWW IN CNAME @

thanks guys I was a little surprised that I missed something so obvious so I thought I'd double check that it is, in fact, okay to do it that way :p
