Re: Auto-notify remote user of IP address change?

Thanks all for that.  I'm going to give dyndns a shot with ddclient.

My original thought was to somehow output the contents of whatismy.com 
to a text file (lynx www.whatismy.cop > .myip ??) and then grep that for 
the part with the IP address and mail the result.  Is this possible or 
am I showing myself up as a hopeless newbie?

Anyway, dyndns looks very promising, so thanks for that.
