![]() ![]() Though there are some limitations, that are described here, it is a simple solution, that doesn’t require any specific knowledge. It checks periodically whether the IP address stored by the DNS server is the real current IP address of the machine that is running INADYN. It gives the possibility to have your own fixed hostname registered on the internet, although your IP might be changing. ![]() We won’t describe the process of signing up and creating DNS records, but you’re always welcome to follow this guide, and ask us if anything is unclear, though it should be. ![]() We will take as a Dynamic DNS provider (you’re welcome to select another one: there is no real difference between them). We’re going to cover the process of using such a configuration with a pppd connection, this package is widely used in Linux with almost all types of Internet connections. In order to prevent IP caching, Dynamic DNS records have low TTL values (e.g. When a hostname obtains an IP address, it is automatically sent to Dynamic DNS system, but users are able to connect using a symbolic name, that remains unchanged (for example, ). When you need to establish connection with a hostname, that has a dynamic IP address (most typical situation – a hostname, that has an unstable Internet connection), Dynamic DNS becomes a simple yet stable solution. Since almost any DNS server provides this functionality, dynamic DNS is used when updates need to be more frequent than usually and updated DNS becomes the most important point in user activity (more than speed, system stability, etc). Dynamic DNS represents a DNS management system, that allows to periodically update DNS records. ![]()
