Hi Guys,
Generally wondering whether its possible to have both a CNAME entry with a " * " to domain and a seperate subdomain mapping i.e. like
* | CNAME | domain.com
bla.domain.com | CNAME | some.example.com
Is this possible or does the * overwrite the "bla.domain.com" and therefore when you enter "bla.domain.com" you go to "domain.com" ?

In BIND, the wildcard matches when another record does not exist. See http://en.wikipedia.org/wiki/Wildcard_DNS_record.
BrianEss : Not just BIND, any RFC 1912 DNS server will do this.Alnitak : RFC1912 is telling _operators_ how not to do wildcards. RFC 1035 is the one that _servers_ comply with.From Warner -
A more specific entry always overrides a wildcard, not the other way around.
For chapter and verse, see §4.3.3 of RFC 1034.
