LAN IP Address Oddity

[John Moniz]

I have a couple of PCs and some appliances (eg. TV) behind a Bell 
router/modem that also acts as my DHCP server. All of the IP addresses 
seem normal (192.168.2.n), but my main PC now has an external IP 
address. It is the same address as for the router. The network settings 
of the changed PC does say DHCP.

I was wondering if anyone could help me determine what could cause such 
a change from the LAN address to an external one? Should I be worried 
about security? And how do I fix it and prevent it from reoccurring?

John.
