Re: IP ranges: This is not guaranteed, especially since many large ISP's have 
absorbed smaller ones and in the process absorbed their IP allocations. Also 
when an ISP gets absorbed, or the internal network management undergoes an 
overhaul, the entire allocation pool could change. Moving ISP's also then 
requires you to change stuff. This is annoying from a support perspective. 
You're better off grepping for the string 'inet addr:', as that should always 
contain the ipv4 address of the system.

However, there are a number of variables that contain various details of the 
connection that are available to scripts in /etc/ppp/ip-up.d/, so grepping 
isn't necessary in this case. The following should work, assuming that mail 
works properly:

#!/bin/sh
echo $PPP_LOCAL | mail -s "My New IP" name at domain.xyz


Good luck!
