I just noticed that the HSMM project is using 10.XXX.XXX.XXX IP addresses for the wireless ports by default is there a reason for using these instead of the amateur radio allocation from https://portal.ampr.org/?

The BBHN firmware automatically assigns RF IP addresses based on the MAC address of the device.  The AMPRNet addressing scheme doesn't provide enough flexibility to do this without adding considerable risk to the duplication of IP addresses.

Well, the safest thing to do is DEFAULT VALUES.  However, what you seek to do can be done.  Note though... there's a reason we warn against making changes to this part of the config. 

 In the Basic Setup screen: 

1. Click DEFAULT VALUES
2. Copy the address the system puts in the IP Address field
3. DO NOT SAVE the default settings
4. Click RESET VALUES
5. Paste the IP address you copied in step 2 into the IP Address field
6. Save changes and REBOOT

If you run into any issues, then you *will* need to DEFAULT VALUES, Save and REBOOT.
