Yeah, it seems like a dynamic ip binding software which provide to those ppl who whould like to setup their own webserver at home.

Before this, I've been introduced to use the service that's provided by www.dyndns.org. But due to the local DNS seems occuring some problem on the configuration, thus, perhaps this software (DnsSite) could help me to do that. Anyway, I never use it before for someone who ever use it, can u please be so kind to share your experience with me or other people who read this post? Thanks!! :P

below will be the link to the tools:

Well, since the software is only supported on Windows, I dont think you will find too many people using it on this message board.
