Assign a domain name to your home web server

Matovu George William
Step 1. Set up your account.
Register for a free account at DynDNS. Agree to the site's terms, and use a legitimate email address to complete registration. Once in awhile, DynDNS will email you at that address asking you to confirm that it continue your service.
Log into your new account. Go to the "My Services" area on the left side. Under "Host Level Services" click "Add Host Services." There, click "Add Dynamic DNS Host." DynDNS will autofill your IP address (if you're doing this from your home computer). Choose a domain and type in a custom subdomain, which can be anything from or or, like below:
Step 2. Set up your computer to update DynDNS.
Now that your computer is registered with DynDNS, each time your computer's IP address changes, it has to let DynDNS know. This can be done either with free updater client software or through your router.
If your computer is connected directly to the Internet, download the DynDNS updater client for Mac or Windows here. Install and enter your DynDNS information so that your computer can update DynDNS's database regularly.
If you are behind a router, you're in luck. Most modern routers support dynamic DNS services. Here's a screenshot from my router's interface (yours will look different) for with DynDNS settings:
Step 3. You're done. Give your new domain a spin!
Type your new domain name by entering it in your web browser's address bar. It should resolve to your home server. From here you can publicize or bookmark your server's new domain name no matter how often your IP address changes.
Notes: DynDNS has a few advanced options to consider.
  • "Enable wildcard" lets you set up sub-subdomains. For example, can resolve to a weblog, where can resolve to a music directory. Virtual hosts must be configured for your Apache web server to display the right site when addressed by different subdomains.
  • Set up an MX record to handle email handling to your home server.
  • Upgrade your account assign a custom domain name or your choosing to your home server as well, for about 25 bucks a year. See more info on Custom DNS.
