Dynamic DNS
To host your server on a changing IP address, you have to use dynamic domain
name service (DDNS).
Anyone wishing to reach your host only needs to know the name of it. Dynamic DNS
will map the name of your host to your current IP address, which changes each time
you connect to your Internet service provider.
Before you enable Dynamic DNS, you need to register an account on one of these
Dynamic DNS servers that we list in the provider field.
To enable Dynamic DNS click the check box next to Enable in the DDNS field.
Next you can enter the appropriate information about your Dynamic DNS Server.
You have to define:
Provider
Host Name
Username/E-mail
Password/Key
You will get this information when you register an account on a Dynamic DNS server.
Click Apply if you have made any changes.
