How should I set up a server to map all subdomains of a domain to an IP?
I wish I could do something like that in the hosts file:
127.0.0.1 *.example.com

5Not in hosts but in your DNS server. – mailq Dec 21 '11 at 21:13

All **subdomains** of parent domain or **hosts** unside domain? They are very different things – Lazy Badger Dec 22 '11 at 04:58

As mailq mentioned, DNS supports wildcard host entries (while the hosts file does not).
A DNS record with the name * will match all names for which there is no other record on that name, returning the wildcard record.
An entry would look like this:
* IN A 192.0.2.1
But, I'm not sure why you'd want to do that pointing to 127.0.0.1 - can you clarify what you're attempting to accomplish with this, and we might be able to point you in a better direction?

mea culpa, think and write in parallel. Wildcard RR haven't relation to CNAME, shure – Lazy Badger Dec 22 '11 at 06:42
