Dynamic DNS
Summary
Dynamic DNS (DDNS or DynDNS) is a method of automatically updating a name server in the Domain Name System (DNS), often in real time, with the active DDNS configuration of its configured hostnames, addresses or other information. This chapter is a summary of the Dynamic DNS function in RUT routers.
DDNS
By default, an unconfigured DDNS instance will be present in the DDNS configuration tab. Below is a picture of this instance. You can create more DDNS instances if you wish to do so by typing in a New configuration name and clicking the Add new button or you could edit the existing instance.
DDNS Configuration
To configure a DDNS instance, click the Edit button located next to it. Below is a screen capture of the default DDNS configuration MyDDNS and a table of explanations.
