Intended for dynamic ip OpenDNS users, this command will update your OpenDNS network IP.
For getting your IP, you can use one of the many one-liners here on commandlinefu.
Example:
I use this in a script which is run by kppp after it has successfully connected to my ISP:
---
#!/bin/bash
IP="`curl -s http://checkip.dyndns.org/ | grep -o '[[:digit:].]\+'`"
PW="hex-obfuscated-pw-here"
if [ "$IP" == "" ] ; then echo 'Not online.' ; exit 1
else
wget -q --user=topsecret --password="`echo $PW | xxd -ps -r`" 'https://updates.opendns.com/nic/update?hostname=myhostname&myip='"$IP" -O -
/etc/init.d/ntp-client restart &
fi
---
PS: DynDNS should use a similar method, if you know the URL, please post a comment. (Something with members.dyndns.org, if I recall correctly)
There is 1 alternative - vote for the best!
If you can do better, submit your command here.

For DynDNS just use ddclient or Inadyn. Inadyn does NOT use https but ddclient does. My fav part of users script is that it uses DynDNS' checkip to update his/her OpenDNS account.
inadyn does a superb job. I prefer it very much to ddns. inadyn allows you to have multiple dyndns domains updated in one instance of the app. ddclient does not. inadyn > ddns imo
shout out to inadyn developers -- great job guys!
+1 for Inadyn > ddclient
@eGGstain Well, I have my own script on my webserver (just a php command, thats all) that returns my IP. And because I don't want to make that too public ;-) , I looked for a command to replace that and used the dyndns one from here.
