Doesn't work, however curl -s myip.dk |grep '"Box"' | egrep -o '[0-9.]+' does work.

The same with wget: wget -O - -q myip.dk |grep '"Box"' | egrep -o '[0-9.]+'

@clockworkavian: Thanks for the tip about whatismyip.org! I don't want to install/use dyndns-client every time I need an IP in a script...

Yep... 1st one works like a charm. No grep or egrep needed. Just Ip plain text. It's perfect. You don't rely on the web designer... Because on the checkip one, if the web designer decide to do any change to the page, it might not work anymore. That's exactly what happened to the propose command on lifehacker, where it is proposed to use myip.dk. This site change the page layout, and bam... The command is useless.

Regarding dynamic DNS update, that is exactly why I am looking for such command. I use ZoneEdit.com, and I have no idea when my ISP changes my IP. I made a script to update the zone every 5 minutes. But I've been blocked by zoneedit.com because I'm making to many updates, even if the site can tell "no update needed" they don't like people "spamming" with update requests. I will now add a command to check by myself if the IP changed every 1 or 5 minutes, and if it did, then I will update the zone at zoneedit.com. Then, every request will be for a good reason :-) This will also show me at what frequency the ISP changes my IP address.
