# DNS with a dynamic IP
|
||
|
|
|
||
|
|
This tutorial is here to help you get around dynamic IP issue. When the IP address change, the DNS service is not update to the new IP address.
|
||
|
|
|
||
|
|
After put in place the solution proposed in this tutorial, the redirection from your domain name to the real IP address will not be loose anymore.
|
||
|
|
|
||
|
|
Make sure you got a global dynamic IP with: [ip.yunohost.org](http://ip.yunohost.org/). Global IP of your box change almost every days.
|
||
|
|
|
||
|
|
The goal of this tutorial is to make the box to say to the dynamic DNS service it has change global IP, then DNS will automatically change.
|
||
|
|
|
||
|
|
If you own a domain name at **OVH**, you could go to step 4 and follow this [tutorial](OVH_fr) because OVH offer a DynDNS service.
|
||
|
|
|
||
|
|
#### 1. Register to a Dynamic DNS service
|
||
|
|
Here is sites which offer a DynDNS service free of charge:
|
||
|
|
* [DNSexit](https://www.dnsexit.com/Direct.sv?cmd=dynDns)
|
||
|
|
* [No-IP](https://www.noip.com/remote-access)
|
||
|
|
* [ChangeIP](https://changeip.com)
|
||
|
|
* [DynDNS (In Italian)](https://dyndns.it)
|
||
|
|
|
||
|
|
Register to one of them.
|
||
|
|
|
||
|
|
#### 2. Move the DNS zones
|
||
|
|
Move the [DNS zones](dns_config), excepted the NS fields, from the [registar](registar_en) where you bought your domain name to the dynamic DNS service you registrer at step 1.
|
||
|
|
|
||
|
|
#### 3. Change Name System (NS)
|
||
|
|
This step consist to say to the [registar](registar_en) that the new DNS service will be manage by the DynDNS service.
|
||
|
|
Redirect NS field to the IP address gived by the dynDNS service.
|
||
|
|
|
||
|
|
Then, remove [DNS zones](dns_config), excepted NS fields, from the [registar](registar_en).
|
||
|
|
|
||
|
|
#### 4. Create a Dynamic DNS login
|
||
|
|
On the dynamic DNS service create a login that you will enter on a dynamic DNS client.
|
||
|
|
This client could be your box or a package installed on your server as `ddclient`.
|
||
|
|
We gone use the client installed on the box which is more easy way.
|
||
|
|
|
||
|
|
#### 5. Configure the box
|
||
|
|
Put the login of the dynamic DNS and the [IP address](http://ip.yunohost.org/) on your box.
