Originally created by @afics on GitHub (Nov 10, 2021).

ip_prefix: fd42::/56 is set in the config.

After trying to enroll a new machine with headscale -n test nodes register xxx I get:

panic: As4 called on IPv6 address

I haven't investigated it further since I made the initial changes, but #208 might be of interest.
