Does anyone know of a script or a program (preferably free/open source) that will check your WAN IP and update an A record in a zone on a Windows DNS server?
An example of this is a small office or home office that has a dynamic IP but hosts a service on a server. The server has a zone for it's records and is primary. The name server is hosted elsewhere but the zone is secondary retrieving the records from the SO/HO server. On the SO/HO server, has anyone heard of a way to check your WAN IP and update an A record in a zone?
The obviously way to solve this problem is static IP addresses, but some ISPs make you upgrade your service to ridiculous numbers before giving you a static IP.
Just wanted to see if this was possible.
