DynDns

ISPs charge you extra for static IPs. It’s worth paying this if you are hosting a server with some non-trivial traffic, but if you just want to occasionally remote-login to your home computer, or try out a cctv solution, DynDns will do the job. For a one-off reading of your current (external) IP, go to What’sMyIP.

On Ubuntu I’m using the ddclient daemon to update the dns entry for my ip address. Detailed examples of sample configuration files (/etc/ddclient.conf) can be found at https://www.dyndns.com/support/kb/using_ddclient_with_dyndns_services.html. Then add to /etc/rc.local the line /usr/sbin/ddclient -daemon 300 -syslog
