Is this router supported with your service

We regret to inform you that Dynu dynamic DNS service is not supported by Netgear at this time. We offer free IP update client software on your computer to keep your hostname mapped to the IP address at https://www.dynu.com/DynamicDNS/IPUpdateClient

In the meantime, we suggest that you take a few minutes to comment on Netgear forum at https://community.netgear.com/t5/Idea-Exchange-For-Home/idb-p/idea-exchange-for-home requesting that Dynu be added to the dynamic DNS service provider list, which will make the IP update easier for you.
