I think you mean IP (Internet protocol) address rather than SIP (session 
initiation protocol, used for voice over-IP/Internet telephony).

Sounds like your router is configured to connect to the Internet on demand, 
and drop the line if it remains idle. The DHCP traffic is contained within 
your local Ethernet so won't bring up the connection, but trying to browse 
the web using Firefox will do so (the requirement being at least one outgoing 
packet destined for the Internet). The ideal solution would be to configure 
your router to:

 - Connect immediately when the unit is switched on
 - Automatically reconnect whenever the line is dropped

See the documentation for your specific router for details. :) If the above is 
not possible then some fairly nasty workarounds would be:

 - Send a packet to the Internet as part of the machine's boot sequence to 
bring the connection up
 - Send a packet every 45 minutes or so, to keep the connection up or to 
re-establish it if it has gone down

For the first, you could try something like "host www.google.com" in the boot 
up sequence (put it at the end of file /etc/rc.d/rc.local), for the second 
you could try "ping -i 2700 www.google.com" launched in the background from 
boot-up. (-i <number> specifies time interval in seconds.) It doesn't really 
matter what command is used, so long as it transmits at least one packet from 
the local network to the Internet.
