Appendix C – Managing a Dynamic Home Internet Address 
 
Accessing the Web Xpander from the internet (i.e. outside your home network) requires 
router specific settings and configuration. Once you’ve properly routed incoming 
connections on port 80, for example, to the Web Xpander you need to know the IP 
address of your cable modem or DSL modem to connect to your location from the 
internet. 
 
One easy way to determine your IP address is to start a web browser on an internet 
enabled PC within your home network and visit: http://www.WhatIsMyIP.com/ 
 
If your IP address is static, i.e. it never changes, you’ll just use that address to access 
resources on your home network. If your IP address is dynamic, i.e. it changes 
periodically, there are a few options available for tracking it. 
 
One free service available is http://www.no-ip.com. No-IP will allow you to create a 
domain name (i.e. http://TheSmiths.no-ip.com) which will automatically redirect to your 
home IP address. If you have a static IP address, you just register that address with No-
IP and choose a domain name. If your home IP address changes, No-IP offers a free 
software utility that runs on an internet connected PC in your home and periodically 
updates No-IP with your dynamic IP address. Once this is established, you can use your 
created domain name to access your home from any internet connected PC.
