Ever since DynDNS.org has dropped all free services, I have been looking for good alternatives. Here in Finland, the IP addresses of the cable and DSL ISPs don't change excessively often, so for a while, it was ok for me to change the A record of my home server by hand in the cPanel DNS editor of my hoster.
However, with autumn and winter came the brownouts and blackouts and, living in a rather small town with a local electricity company which is not very dedicated to continuity and good service, quite many of those. That naturally lead to many reboots of my router and thus many new IP-addresses. At this point, changing the A record by hand became rather tedious.
