No-IP: Managed DNS. Make a Dynamic IP into a "static" one.

 Case Study: Unless you have (pay for) a static IP from you internet provider, they can (and will) switch your IP address on you.  Why is this important you ask?

• Have you ever wanted to host a website/services on your home computer?
• Have you ever wanted to remote into your computer, without paying for a service like GotoMyPC?
• Have you ever wanted to have a URL that points to a hard to remember IP address?

Solution: No-IP.com has a free services that you can pick a URL from a bunch of different sub-domain names.  (for example telluridetech.no-ip.com).Then you run a Dynamic Update Client (DUC) which will continuously check for changes to your IP and will automatically update their managed DNS info.  Then when you go to your chosen URL, it will point back to your computer.Hmmm?  you ask.  Lets run thru this step by step.

1. You register a URL with No-ip.com and set up an account.  Lets say telluridetech.no-ip.info . 
2. You download a Dynamic Update Client (Windows, Mac, Linux) and install it on a computer that stays connected to the internet.
3. Your run this program in the background.
4. You give out your new "hip" URL to your grandmother.
5. She puts it in her browser, and now she is at your webserver (ok, I did not include steps, like firewalls, setting up webservers, etc).  But the point is she was able to get to the front - door, because No-IP is managing/updating the IP
6. Lets say then your internet provider switches, your IP address on you.
7. No-fear, because the DUC probably has caught this already and updated NO-IP with the new address.

And the best part about this is the basic service is FREE.  Cant beat that.Good luck...
