I've been following this thread concerning dynamic IP's and how to deal with them. (formerly under subject of DSL and sendmail) I took a look at www.dnstogo.com this morning and it looks interesting. The big problem I see with many of these services, however, is how to furnish the service with your new address with an automatic script. dnstogo, for example, uses a web style interface for non windows systems and an automatic client for windows systems. I think I will contact one of these services to see if there is a way we could give them the address with a script of some kind or perhaps release the source code of the windows client so it could be ported with some hard work:). What are the names of some other dynamic IP services we can check out? I've heard of this dnstogo, dynip, 2y.net (couldn't resolve lookup)
