ActiveDNS is our dynamic DNS service for use locally in SA. It keeps a domain name up-to-date with a the changing IP addresses that you ISP gives you. This is so that you can access machines (at home or at work) that are connected to the internet by ADSL. Not recommended if you require 99% uptime but great for backup systems or for fault-tolerant networks exploiting cheap local bandwidth.
ActiveDNS supports the DynDNS2 protocol which means that you can use any DynDNS client to keep your IP up-to-date. On Linux or similar systems use ddclient. If you’re on Windows and don’t need anything too complicated then use our very own ActiveUpdater. Head over to the ActiveDNS site for more info.
