Super Simple Dynamic DNS Updater - SSDDNSUpdate.bat

2019-12-26 Version: .2 Second Release, NsUpdate.info Compatible

~~#### 2019-12-24 Version: .1 Initial Release

DESCRIPTON:

A simple way to update dynamic dns hostnames on Windows for compatible providers.

Works with a list of URL's in a text file and uses wget to set the updated ip for services that supports such methods for updating DNS records. As long as the dynamic dns provider gives you a "direct update url", this program should work for it, its Super Simple.

The SSDDNSUpdate.bat connects via wget to those URLS and updates your dynamic dns records on the provider.
