In short, I have a DHCP server running on an Linksys Router.

That's just it -- there isn't any interaction unless something else adds it. This is the case for NetBIOS as well, it is a naming/browsing system which works in isolation from DHCP. It would behave the same if you manually assigned addresses or ran an auto-negotiating protocol like IPX or AppleTalk. There are solutions to put DHCP assignments into DNS, ranging from simple bash scripts to full-on products; back in the mid-90s a firm called American Internet Company sold a product called DNS Registrar which did this and integrated with an NT Domain or LDAP user directory too. Cisco bought them and I believe the product has the same name. It's expensive. If you really care, the best solution is to edit DHCP's config and tell it to always assign the same IP to a given MAC address; then you put that IP into DNS and call it a day. -- Jack Coates Monkeynoodle: A Scientific Venture...
