Hi all,

I've recently set up a small box to run cups, to provide network access 
to a USB-only printer. It's a 32-bit machine running bullseye.

I'm seeing log messages like these:

> Mar  7 15:47:47 whio avahi-daemon[310]: Record [Brother\032HL-2140\032\064\032whio._ipps._tcp.local#011IN#011SRV 0 0 631 whio.local ; ttl=120] not fitting in legacy unicast packet, dropping.

Those link-local IPv6 addresses belong to the machine itself. It 
currently has no other IPv6 address(es) (other than loopback), but I 
should probably set that up.

Any hints as to what's going on?

Most of the hits I get from a web search are full of 'me too' with no 
answers.

Cheers,
Richard
