You need to determine who your DNS companies are. Make use of a public whois server or perhaps your own whois(1) client and search for the "nameserver" records. Knowing who your nameservers are, then use their administrative interface to include the best IP addresses for hosts inside your domain, along with the reverse pointers if required.
