What is it?
DNS stands for dynamic DNS, or more specifically dynamic Domain Name System. It's a service that maps internet domain names to IP addresses. It's a DDNS service that lets you access your home computer from anywhere in the world.
Why do I need it?
DDNS is a handy way for you to refer to a server/router with an easily rememberable name, where the servers ip address is likely to change when your router reconnects or reboots, its ip address is set by the provider of that connection, this means it may update at any time.
How it works?
The Dynamic DNS monitors the IP address for changes. When the address changes (which it will if you have a dynamic IP address), the DDNS (or DynDNS) service updates your new IP address.
Why is it useful?
It can be very useful for people who want to host their website, access CCTV cameras, VPN, app or game server from their home computer. It is cheaper than to have a static public IP and by setting up Dynamic DNS, you will avoid the need to update all of your records whenever your IP changes manually. Also, static IP address is not always an option; it depends on your Internet provider.
Dynamic DNS is a very flexible option. The way that Dynamic DNS gives a connected device the ability to notify DNS servers to automatically update, alongside the active DNS configuration, IP addresses, configured hostnames and some other information. This saves the need of administrator who should do the changes.
How to start? step by step.
The simplest way to use this DDNS service is :
- Login then go to your account.
- Create your hostname.
- Download the update client software from your account menu.
- Install the client software in a PC or smart phone that is connected to your home network.
- Use the token of the hostname you just created in the client IP updater software configuration.
What is a hostname?
A hostname is the label (the name) assigned to a device (a host) on a network and is used to distinguish one device from another on a specific network or over the internet. The hostname for a computer on a home network may be something like new laptop, Guest-Desktop, or FamilyPC.
Our free dynamic DNS service offers free hostnames on our domains dyndns.dyndns.life.
What is the update client software?
An update client is an application that keeps your hostname’s IP address up-to-date. The update client periodically checks your network’s IP address; if it sees that your IP address has changed, it sends (updates) the new IP address to your hostname in your Dyndns account.
What is Port Forwarding??
Your router has a separate network interface that connects it to the internet. This interface has an address which is assigned by your ISP. Computers inside your home network cannot access directly the internet. They should be forwarded (routed) by the router using a functionality called Network Address Translation (NAT). This allows the multiple computers inside of your network to appear to the internet as one computer with one address and different ports. You may find how to forward the ports of your router in this guide https://portforward.com.
Does my hostnames expire?
Free hostname never expires. However, if it is not used for a period of 1 year, then it will be automatically deleted.
Is one hostname enough for all devices in my network?
Yes. From the internet, you can access your webcam, security camera, DVR, file storage, thermostat, computer, etc... using one hostname. You only need to do port forwarding in your router for every device you want to reach.
Is there a Premium Dyndns version?
As of the end of 2019, we do not provide Premium Dyndns version of the service.
What is the admin password?
Admin password is used to access the dyndns management interface (http://dyndns.life/admin).
what happens to my data?
this goes into a private database and will never be sold on.
can I use this for my email server?
Yes, you only need to create the MX record for your hostname in the management interface. If your ISP is filtering port 25 then you may use an SMTP relay.
Can I create multiple free dyndns accounts for my home network?
Technically, you can. However, this does not make sense since you can use a single account to update as many devices as you want in your network. For that, you only need to change their ports in your router setting. Multiple accounts linked to the same public IP address in the same time will be deleted one week after a warning email is sent to the account owner(s).
What If DynDNS isn't in My Router or Device?
Waiting for your device manufacturer to update its dyndns list with DynDNS, you can simply download our Dynamic Update Client, which is available for Windows, Mac, Linux . Install the software at the location where you would like your IP address to be updated with your hostname. The Dynamic Update Client must be running at all times in order to keep your hostname updated with the current IP address.
I am lost. I don't know how to use the service
