Yeah, configure your own DNS server and ignore theirs. At the very least, configure a cache-only DNS server or a forwarding DNS server. The O'Reilly books on "TCP/IP Network Administration" and "DNS and BIND" will be very helpful to you. Start with the TCP/IP book and buy the DNS book when you run out of help in the other one. -- "Where am I, and what am I doing in this handbasket?"
