I'm curious as to the process of how a mesh node chooses its wireless IP address. Is is simply randomization with a check to ensure it's not currently in use on an existing mesh? Or is there some sort of correlation between the IP and the serial number or some other information in the hardware of the node?

If it is randomization, does a node try to retain the same IP address after a power cycle or does it select a new random IP each time?

The wireless IP address (10.x.y.z) is set during the initial setup of your HSMM-MESH™ node where x.y.z is the last three bytes of the wifi MAC address of the router.


For instance, say your router's MAC address ended in :12:17:48 Convert those from hex values to binary, your router's wifi IP address would be configured to 10.18.23.72


This is done automatically during the firmware installation so you shouldn't have to do anything yourself to set the IP address.

Thanks for the reply! As a software developer, that makes very good sense and I am comforted knowing it's not just a random selection. The odds of a duplicate seem to be about one in 16.7 million or so. I'm liking what I see the more I see of this.
