If you want a free, faster, more reliable and secure DNS, use OpenDNS.com
All you have to do is change your DNS entries to:
208.67.222.222
and
208.67.220.220
and if you sign up with a free account, you can also block unwanted 'stuff'.
Every computer should be using the OpenDNS servers.
As for your question, I'm not sure I understand, either. Is your home computer a server? Or is your home computer a G4?
