[ale] How can I determine my own dynamic IP domain name?

[aesop]

When pppd connects, it will run /etc/ppp/ip-up.  The 4th argument to this 
script is your local ip address.  Likewise, pppd will run 
/etc/ppp/ip-down upon termination.  Read the man page for pppd.  Search 
for ip-up for all the parameters.
