Is so-called 'DHCP MAC Randomization' enabled?

I'm not sure? Why should such a crappy stuff be enabled by default? It's a nearly blank installation, only minimal changes was made?
And of course nothing related to "DHCP MAC Randomization" ...
Sorry, I forgot to say, that I was speaking about the ethernet interface, wlan isn't involved at all!

If it is, your client will do a REQUEST for it's old IP address, but use a new random MAC address.  The DHCP server will reject the request as the previous MAC + Address pair don't match what is being sent.
The client will therefore re-request an IP and the server will issue it from the next available pool IP.

The DHCP-server is a machine running DNSMASQ - it never shows the behaviour to pick "allways the next IP" before - in every other case it has always picked a random address from the reserved pool, if it sees a new MAC-address.

I've just installed 'devuan_chimaera_4.0.0_arm64_rpi4.img.zip' on my Raspberry 4.
During startup/init I see, that it pulls an IP-address from my DHCP, let's say 192.168.2.112.
During login-prompt I see that it get's another address, it's always the next (in that example 192.168.2.113).
On next boot it gets the "113" first and few seconds later the "114" and so on ...
I wouldn't call that "normal behaviour", but what can bei done against?
As far as I remember older "beowulf"-versions didn't do so?

Thank you, FM_81
