RealDNS 7.4.3 – Dynamic DNS update client


RealDNS is an application that updates your hostnames with the latest IP address of your computer assuring that you will always have an updated hostname allowing you to connect to your computer from everywhere.


The IP address, which will be used to perform the hostname update, can be: 

  • External
  • Gateway
  • Local
  • Manually defined


The application has an initial easy to use interface for every user but behind it the application contains powerful tools for professionals.


Provider failover – this option allow you to make hostname updates to multiple providers at the same time, so in case a provider will be down your IP address will be saved to the other enabled providers assuring that you will always have a hostname updated with your latest IP address.


Internal failover – if the interface assigned to your hostname is not available the application will get the IP address of any available network interface and perform an update with that IP, thus maintaining a connection to your device, with two failover types.


Multiple account, multiple hostnames, multiple IP sources – Use the IP address of any available interface in your system and assign it to any hostname from any account. Every hostname can have his own IP source.
