Ever been at work or at a friend's house and wanted to log into your home connection? Know the IP address off the top of your head? Well, if you're like me, then you probably don't remember it. Even if you write down your current address, it will likely change on you by the time you need it.
To make this easier, your ISP will assign you a dedicated IP address. This will allow you to always have the same address and make it easier to connect to your home network. Problem is, they will want to charge you a monthly fee for the privilege.
Fortunately, there is a free service available to make it possible to get by without a dedicated address. The concept is called Dynamic DNS and the website that I use that offers this service is called DynDNS.
Basically, the way that this works is that a central party keeps track of your computer's IP address. By downloading a special client to your computer, you can configure it to send an update to DynDNS whenever its address changes. This allows you to use DNS to easily recall the exact address that your home computer is using at any time. DynDNS is easy to setup with the hardest part being choosing which of the 80 domain names that you want to use.
This should allow you to find your home network on the Internet. Next, I'll cover how I securely connect and encrypt all communications to my home network.
