This doesn't appear to be an IPv6-specific issue. In principle named should
also be capable of listening on all of 127/8, but I can't find any
configuration syntax that will do more than listen on 127.0.0.1. I can ping
127.0.0.2 (and so on) but even explicitly adding listen-on 127.0.0.2 won't
cause named to actually listen there.

Subject: Bind listener to an IPv6 from AnyIP subnet
Hello, I am trying to bind named listener to an IPv6 from prefix which is
assigned to a system via AnyIP kernel feature - basically, it is done by the
following command: sudo ip -6 route add local 2001:db8::/32 dev lo.
To be able to use IPv6 from AnyIP prefix the following sysctl must be
applied: net.ipv6.ip_nonlocal_bind = 1
Having above, I am able to use any IP from AnyIP prefix in all software but
named refuses to create socket, which listens to that kind of an IP address.
As an alternative approach I have tried to run with a configuration
"listen-on-v6 { any; }", but it does behave in a way I need - it binds separate
socket for each discovered IP address rather wildcard address of [::].
Had anyone faced the same or similar issue?
