what is CNAMEs (i am new user)

Thanks

CNAME stands for "canonical name" and is a record which lets you map an alias to it`s canonical name.
An example:

www.mydomain.com CNAME mydomain.com.

In this example www.mydomain.com is replaced with the canonical name mydomain.com which is then looked up by the resolver and the ip is sent back to the client.
This lets www.mydomain.com resolve to the same ip as mydomain.com.

The other day I read that "cname`s are evil". That might be an overstatement, but my own experience is to use A records instead of CNAME`s, whenever possible. Ofcourse, these simple rules apply:

- No ip`s in CNAME records

- No canonical names in A records

Hope this helps.
