Hi I'm using an ADSL modem that is also a router (Dicksmith one). In
WinXP under DOS, I can type 'ipconfig' and it will tell me my local ip
and my wan ip. I've been looking for similar command that'll give me
the information.

I need this to do dynamic DNS. At the moment I'm using an external
service to tell ddclient of my WAN address.

I think its better if I can obtain the information from command line
rather than from an external website. But perhaps that's how DOS
ipconfig does it? hmmm
