I haven’t tried this personally. But backfillips may work for you. Alternatively you could perform an UPDATE statement on the DB.

I'm not sure if I understand your question in full, please consider carefully.

By default, Headscale assigns IP addresses sequentially. If you currently do not have any holes in your IP address assignment, the following should work (did something similar on 0.22.x):

• Delete a node from headscale
• There is now a hole somewhere in the middle in your range of assigned IP addresses
• Register the "same" node with headscale
• The previously removed IP addresses should be picked up by the new node
