I use NetworkDLS’s DNSLife because it’s easy to install, it runs as a service and it has some pretty advanced features. Also, I wrote it - so full disclosure.

I could sauce 3 or 4 pizzas in that time just from watching others donut. Ladle in the sauce and quickly spread it around with the back of the ladle. This is pretty asinine.

DNSLife is (my own) easy to use and free dynamic DNS service for Windows. Simply download, install, sign-up and choose a sub-domain and parent domain.
