Just for a different take on this...
In cases where you don't want to link a domain name to the dynamic IP, you can set up a cron job to send you the IP address via e-mail.
Incidentally, I can't think of any arguments - security wise - against using something like dyndns, but I can't say I've put a great deal of thought into it. I set up a cron-job script mostly out of curiosity than anything (the 'there must be a way' motive). Anyway, my script (which borrows the key part from Douglas Ward's - thank you Douglas) looks like:
---start script--- #!/bin/bash #get the current IP address for this connection off the internet and mail it
to="[EMAIL PROTECTED]" subject="IP Address for x"
#this next bit is on one line
curl http://checkip.dyndns.org/ 2>/dev/null | grep "Current" | awk '{print $6}' | sed 's/<\/body><\/html>//' | sed 's/\///' | mail -e -s "$subject" "$to"
---end script---
It works perfectly for me. Next thing I'm going to do (out of curiosity, best way to learn) is output the result into a file and then only send the e-mail when the IP address is different to what's in the file - i.e. only send an e-mail when the IP address changes.
Cheers,

Hi folks,
I would like to get an remote IP. It's about my girlfriend's computer where I share some directories and install some packages. The problem is that all the time I need to connect via ssh into her computer I must call her asking for its IP provided by her ISP throughout ifconfig output. What can I do in order to get the IP from her computer all the time the machine is booted? Is it possible to send a message by email, SMS or whatever way to do that? Further, her computer is connected by a ADSL (dinamic) and my computer uses cable modem (dinamic also).
Best regards,
Romulo Sousa
