care to actually write a full post? your title alone is not exactly insightful.

You should really give more information on your question, people normally respond a little better when you do...(the above post is a perfect example) Anyway, you might check out DynDNS . Here's a direct link to the Dynamic DNS page:

Good luck!

what more information do you need?

what you think "a DNS" means for a start...

DNS is a server that convert a domain into a ip address.

Boy, this is a funny one.

What we're looking for here is what are you trying to resolve. Are you wanting to build an internal DNS server? Do you simply want a dynamic DNS service to tie a real-world domain to your public IP address and have that record update every time your public IP changes?

I'm guessing the latter. If that is the case, you've got a perfectly good solution already provided in DynDNS.org. I am using their service and LOVE it. You setup an accound with them at a cost of $0. Choose one of their domains and tie in a hostname of your choosing (ex myip.dyndns.org). Once you have that, you research a client to update. Some broadband routers can do this automatically for you; my Linksys WRT54G can do it. I use a smoothwall for my outside firewall which is updating my record for me now. There are also clients available for Linux and Windows that can query routers and websites to get the outside IP and update for you even if no interface on that box has the public address.

DynDNS.org has some pretty good documentation on the different clients available for their service.

I hope this helps.

I guess the $64,000 question is: what do you want it to DO?

babyloss, let's start anew. Something went wrong... it happens, sometimes...

Well, please choose at least one of the following:
A- You have a single PC, with a dynamic address given to you by your ISP, and you want your PC to be reachable from anywhere.
B- You have a single PC, with a dynamic address given to you by your modem-router, and you want your PC to be reachable from anywhere.
C- You have at least 2 PCs, that have their IP addresses given to them by your modem-router, and you would like to access one PC from the other using its name, not its IP (which may change over time).

Yves.

D- you want to cache outside DNS queries for faster response times in the future.
