Ip addresses not updating thru dyndns

This makes it pretty difficult to pull the same trick that is so easy for the likes of Coca-Cola because the address you have today isn’t the address you might have next week.

Thankfully DDNS providers make it dead simple to assign a memorable name to your home IP address because they update automatically as your IP address changes over time.

you want to resolve to your home IP instead of yourpersonaladdress.no-ip.net).

There are also other features like multiple sub-domains so you can set up multiple addresses like music.yourpersonaladdress.com, minecraft.yourpersonaladdress.com, and so on.

Let’s take a look at how to set up a simple DDNS account with Dynu, point it at our home network, and set up automatic DDNS entry updating.

Although we’re using the Dynu web portal and settings, the general setup process is nearly identical across providers and can be easily adapted (consult the support files for your provider if you need additional help). Enter the hostname and domain name you wish to use, here labeled “Host” and “Top Level”. If you wish to use your own domain name you can also enter it here and follow the instructions for linking your domain name to the DDNS service.

Before dive into the tutorial and before we even start talking about what dynamic DNS (DDNS) is, let’s start with the basics–what DNS even is.

DNS, or Domain Name System, is the magic that makes the internet user friendly, and the greatest thing since sliced bread.

Let’s look at the next important step: setting up your home network to automatically update the servers for you.

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 123.123.123.123, and are not particularly easy to remember.

Creating the actual DDNS entry is only half the battle when it comes to time saving and convenience. Let’s look at how to automate DDNS updates at the router and the desktop level. Open the drop down menu, as seen below, and select “Custom”.

We’ll be using a D-Link router running the fantastic third-party DD-WRT firmware to demonstrate, but the settings are pretty standardized across all routers that support DDNS–consult the documentation for your router or firmware to find out where the DDNS settings are, or just poke around the settings until you find them. As you can see DD-WRT (and many other routers) come with pre-configured entries for various DDNS services but the custom entry offers the most flexibility (if you have it). Your router will now update the DDNS server every time your IP addresss changes (and, even if it hasn’t changed, it will still connect to the DDNS server every 10 days, per the “Force Update Interval” to check in).
