I'm not entirely sure if this will solve your problem but you can set up a FQDN for that IP without causing any conflicts. If you have a "public" domain name, say, yourdomain.com than you could set up a subdomain private.yourdomain.com and locally run your own DNS server to serve for that domain, and to forward DNS requests for all other domains. You can also make that some local DNS server do reverse lookups in 192.168.0.0/16 without worries as long as DNS queries are only coming from within your local network. Also, try to configure your DHCP server (on your modem-router) to always give the same IP address to your laptop (you can do this by associating an IP with the hardware ethernet (or wireless) MAC address. -j -- Jeffrey Goldberg http://www.goldmark.org/jeff/
