I have two PCs at home with two different Internet connections. I want to use a remote desktop connection, but my IP address is dynamic.

Is there any software I can install on Windows XP, which can solve my problem?

I tried Logmein, but it's not as easy as Remote Desktop.

Get a free account on DynDNS and use their Dyn Updater

Any dynamic DNS provider should work.

Here's a fairly big list: http://www.inatech.eu/inadyn/dyndns_list.html

Some routers or router firmware (like Tomato and DD-WRT) provide dynamic DNS features, so it means you don't need to run the provider's dynamic DNS software on one of your local PCs. Useful if you're NAT'ing several PCs.

You can get free [sub]domains from no-ip.com, which you can use instead of IP addresses when connecting to your computers through RDP.

They have a DNS Update Client, but many routers have the ability to send IP updates to no-ip.com and other DDNS providers.

If you already have your own domain, you may prefer to use ZoneEdit, which is what I have been using for the last two or three years instead.


As the title of this question may bring other people here who are looking for something a bit different, this is a script I made to show your public IP address from the Windows command line (you need wget for it to work):

@echo off

:: WhatIsMyIP.cmd

if [%1]==[-h] goto :HELP
if [%1]==[--help] goto :HELP
if [%1]==[/?] goto :HELP

wget -q -O %temp%\MyIP http://automation.whatismyip.com/n09230945.asp
for /f "delims= " %%G in (%temp%\myip) do set PublicIP=%%G & del /q %temp%\MyIP
echo. & echo Your public IP address is %PublicIP%
if [%1]==[--clip] echo %PublicIP% | clip
goto :EOF

:HELP
echo. & echo Usage: whatismyip [--clip]
goto :EOF

:EOF
