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.
