I'm outside my area of expertise here, but I have a feeling that what you are trying to do needs dynamic-DNS support in the DNS server. Ie the ability for client to add/alter DNS records. Dnsmasq doesn't provide that facility. Adding it would be a major undertaking. > Any suggestions? I'd prefer to keep the > host pointing at the WRT54GL as its primary DNS server. Use server=/<domain>/<server> to forward the domain in question to a DNS server which supports dynamic-DNS. dnsmasq should have no problems _forwarding_ DNS-update requests, even if it cannot act on them.

The I don't know Windows much (does anyone??) but I think this is their implementation of RFC's 2136 and 3007. I know that on my ISC named, there's one Win2K client which is being logged as it attempts to register itself in DNS. I presume the ISC named wouldn't see / understand this if it was being done using some proprietary method. I wouldn't expect dnsmasq to implement these RFC's. If it did, we'd find our beloved dnsmasq was as complex and difficult as ISC dhcpd + BIND. :) Hey, I *like* ISC. But I also like ... hearing fingernails on chalkboards![1] ;) Seriously, the ISC solution has its place, and dnsmasq occupies a different niche. I think it should stay that way.
