Dnsdynamic.org DDNS configuration


This chapter is a guide on configuring a dnsdynamic.org provider DDNS instance on RUT routers.


There is one mandatory precondition for DDNS to work - you must have a Static or Dynamic Public IP address. Dynamic DNS will not work with a Shared Public IP. You can read up more on this in our article on Private and Public IP Addresses.

The easiest way to find out this information is to log in to the router's WebUI and check the WAN widget in the Overview page. You will be automatically redirected to the Overview page after you log in and the WAN widget will be on the right side of the page, second widget from the top. If the WAN widget displays a Public IP address, your DDNS configuration should work; if it displays a Private IP address, that means you're using a Shared Public IP address and you won't be able to reach your router with the help of DDNS.
