Every computer attached to the Internet has an IP address. Name Translation is the process of relating a name (like 'www.google.com') to an IP address (like '18.104.22.168') so that a website (or other service) on a computer can be accessed using an easily remembered name, rather than the IP address number of the computer. Name Translation is implemented via a distributed database known as the Domain Name System.
This database is implemented on the Internet by DNS name servers which keep track of DNS records and exchange this information between each other to maintain consistency. Every request for a name (ie. a web browser) is then directed to one of these name servers.
Most servers on the Internet have a fixed (static) IP address that never changes. The DNS record for this node will only change infrequently.
However, many home users are assigned an IP address that changes more frequently. These dynamic IP addresses are assigned by an ISP. This makes it a challenge to translate a Name to one of these IP addresses.
A number of DNS name servers offer a method to update the DNS database with dynamic IP name translations. This is accomplished by using a small software utility on their computer or a local router.
These Dynamic DNS services allow the user to choose a hostname and set an initial IP address to correspond to that hostname. The software utility then periodically checks for a change to the computer's IP address, and when a new IP address is discovered, it updates the Dynamic DNS database to reflect that change.
First you need to install my repository, see how to do it
then you can install my module
yum install nethserver-ddclient --enablerepo=stephdl
you have a bundle of dyndns providers, some are free of charge, others are not. If you think that more providers could be added, please raise an issue in github and provide the dydns configuration (GG is your friend)
When your providers is not listed, you have custom fields to fill but in case of specific settings it is possible that it doesn't work → raise a bug
Please raise Issues on github
