DDNS requests - DDNS sends a request every 3 seconds
Orbi RBR50 v2.5.1.8 DDNS (No-IP) is sending an update back to the mothership every ~3 seconds. An analysis of DNS traffic shows a majority of all traffic for the router is going to ipcast1.dynup...
Something to contact a forum moderator about and see if they can relay this to NG engineering to see if this is by design or can be adjusted.
An update: Pulled the USB stick this morning after collecting more than 15 hours of WAN traffic. I concur that Orbi appears to be far too busy talking to dynupdate.no-ip.com. Every time Orbi asks, "What is my IP?", that involves a whole sequence of DNS queries (where is no-ip.com?) TCP connects/acks, and finally the http "get" and the response. My understanding was that Orbi was acting as a DNS server and caching IP addresses, so I do not understand this part at all. Then, at intervals of an hour or half-hour, Orbi uses http to get the entire parameter set from no-ip.com. That includes the email address associated with the account and all of the host names that are registered with no-ip.com on my account (Wow. Had not expected that.) What I did not see in all of this was any move on the part of Orbi to update the no-ip.com database. This makes sense as my IP address has not changed in months.
Will be interesting to learn if making changes on the no-ip side have any effect.
p.s. Invest in a 32GB USB stick and you can learn far more than you wanted to about what is going on in the network the Orbi is connected to. A lot of packets flying around that make little sense. And a lot of connections from inside my network to places I have never thought of.
