Mapping all subdomains of a domain to an IP

  • 772

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
ip configuration hosts

    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?
