Title: Kea IPv6, random allocation missing?
Post by: Aerowinder on January 24, 2026, 03:53:14 PM
Greetings,

I switching to Kea IPv4 when it came out, and then IPv6 when that version came out, been using them ever since. I noticed that with IPv6, Kea would assign new addresses in numerical order - ie. ::1, ::2, etc.

There was a patch pushed to GitHub to allow random allocations, and this patch made it into a more recent release (don't remember which one, exactly), which would assign you "random" addresses, but they would remain "sticky", similar to how ISC DHCPv6 server worked.

This option seems to be missing in 26.1. Is it default now?

Hi again,

In subnets under advanced settings, see https://github.com/opnsense/core/commit/65bd273b33

It was added in 25.1.7 so many months ago :)


Cheers,
