Is it possible to know/resolve multiple DNS names to IP "wildcard like"?
Solution 1:
It cannot be done, at least not easily. In order to know what servers are registered in a domain, you would need to ask those from the nameserver, which would mean a zone transfer, which is something most sane DNS server will deny. You can guess or harvest host names, but there is no way to explicitly enumerate all hostnames in a domain without having access to the DNS server of that domain.
