DynSite automatically updates your dynamic IP address every time it changes on one or many dynamic DNS services or by email. This allows anyone to connect to the servers running on your own computer using a fully qualified domain name. Since your host name never changes it makes accessing your servers much easier than using your IP address which changes each time you reconnect. This is also useful when you want to remotely control your PC.

Dynamic Update Tester is an application to test dynamic updates (RFC2136) on DNS servers. The latest version supports secure updates using transaction signatures (RFC2845). This is a test application not an automatic IP updater. For an advanced dynamic IP updater please try my DynSite program available at http://noeld.com/dynsite.asp
