Free Way to Create Dynamic DNS

Dynamic DNS (DDNS)? This is a system that enables you to have dynamic IP address points to fixed domain name, so you don’t have to worry about domain name issue when the IP is changed as the domain name will point to new IP always.

If you have home network and connects to Internet by using DSL/Cable broadband connection with dynamic public IP, then you can make use of this DDNS to host web server, email server and other server by just using that dynamic public IP. Or if you have several web servers that tie to different public IP, then you can point the domain name to either one of the server IP and make system maintenance on other servers.

Interested to get one DDNS to use at home? Ok..I will show you how to register a free DDNS on www.DynDNS.com. Below are the free DDNS services provided by this website:

- Get five (5) hostnames in 88 available domains for free.
- Create wildcard CNAME *.yourhost.dyndns.org for yourhost.dyndns.org.
- Forward web requests or mark host offline for maintenance or downtime.
- Configure MX records for flexible mail routing.
- Update host using ddns update clients for a wide variety of platforms.
- Modify DNS TTL values for fast propagation or reliable static IP caching.
- Deliver your DNS records to 5 DNS servers in 5 tier-1 datacenters around the globe.

First you need to create an account on this DDNS website, then proceed to this DDNS link and click Get Started button. After that key in your username and password to proceed.

Ok..Once you reach the following DDNS page, you can proceed to create your DDNS record. As an example, the hostname I choose is picohat and my dynamic DNS name is homeip.net. I also enable Wildcard and my Service Type is Host with IP address. Finally I key in my DSL broadband IP (60.54.61.117) as IP Address. I don’t enable Mail Routing because I don’t have any mail server in my home network. Click Create Host at last.

Note: You can always click that ? symbol in order to learn more on the DDNS settings, such as what is WebHop Redirect, Offline Hostname, etc.

After that open the command prompt (cmd.exe), and try to resolve and ping the new domain name. For my case, I able to resolve the picohat.homeip.net to 60.54.61.117 and also can ping picohat.homeip.net. So it’s working!!!
