You get this ip address by DHCP from the netopia router, not from
Eircom. If you want to test that, remove the DSL line from the netopia
and see for yourself.

This is the fixed ip address of the netopia on the lan side of the router.

On the wan side of the router you will probably get a different ip
address every couple of days. You can see your public ip address by
So eircom gives your netopia a public ip address by PPPoE, and you get
a private IP address from your netopia by DHCP, but on the lan side of
the router while Eircom are configuring the wan side of your router.

You would probably be best giving your PC a fixed ip address of
192.168.1.253 if you want a fixed ip address on your lan. Netmask
255.255.255.0, gateway 192.168.1.254, and DNS server 192.168.1.254
should work just fine.
