I understand why they did it; they wanted to increase their profits.
However, the problem was that there were many how-to guides out there that referenced Dyn DNS’s free service; there were many hardware devices such as routers and IP cameras that were hard-wired to use Dyn DNS.
The simplest method possible would be through Lu CI (the default web UI for Open Wrt). There are other scripts and programs available in the web, also some DDNS providers offer their own programs.
All of them are currently not ported and tested on Open Wrt.
Every internet-accessible resource–web pages, FTP sites, you name it–has an IP address that serves as the resource’s network address on the internet.
These addresses are numeric, in the format 126.96.36.199, and are not particularly easy to remember.
Sometime around November of last year (2011), the popular Dynamic DNS provider, Dyn DNS severely limited their free account offerings (See reference link #1 at the bottom of the page).
If it is not enabled, enable it to check the password. If you don't specify any IP, the IP from which you are accessing this URL will be set for the domain.
Simply put, using this service gives a name to your IP. Users won't need to discover what your new IP is, they can simply type your domain name.
So if you're hosting something on your line, people would not have to bother typing your IP. This guide will help you configure your DDNS service, so that your router auto-updates your IP to your DDNS provider.
Today, I’m going to show you a loophole that still allows for you to get a free Dyn DNS account.
While exploring the options of my D-Link router, I came across Dynamic DNS page.
