I'm trying to find the WAN IP range for a network on another location. When I do a tracert on the LAN gw, the last hop is the adress is, This is the ip range belonging to the ISP, but I didn't think a Wan adress would end With 255?

I know tracert will not allways find show the WAN IP. I'm not on this network, so I can not take a html request. Is there somthing else I can do to check?
