Getting my IP address when not at home...

Nakatomi2010

I have a customer who needs to be able to log into their computer remotely, and basically get something like an e-mail a day that tells them what their external IP is at home.... Or some way to get their IP address of their home computer while not at home...

Thanks...

If he doesn't have a static IP address, this program should help him:
http://www.no-ip.com/services/managed_dns/free_dynamic_dns.html

Basically, he installs a program on his computer that detects what IP address his ISP has currently assigned to him. No-Ip.com assigns a free domain name to him, username.no-ip.com. When he types in that domain in a browser, it'll forward him to whatever his computer's current IP is. Your friend could always just ping the free domain assigned to him and see what the current IP address is.

Sign up for a dynamic DNS service like DynDNS or No-IP. They will give you a generic DNS (like nakatomi.dyndns.org) and you install a small client program on your PC that runs in the background and sends an update to their server to forward your IP to the domain name every time your IP changes.

Also, some routers support DynDNS and No-IP natively, so depending on your client's router make/model/firmware you may not even need any software as the router will keep the service updated on its own.
