localhost name lookup

[Eric]

That is means that the 'domain' is reserved and can be used locally. It doesn't specify all records in that namespace / domain will resolve to 127.0.01.

Think of it like .com

If you want every A record in *.localhost to resolve to 127.0.0.1 what you did will do that.
