Hi, reviving an old thread with some new information:

See with ifconfig or ip addr show. Diarmuid didn't say what platform he's running BIND on. This may make a difference wrt. a bug I recently stumbled over: https://gitlab.isc.org/isc-projects/bind9/issues/589 This will typically hit the BSD lineage of OSes (NetBSD in my case), which will refuse to apply an IPv6 control header on a socket used for IPv4. The particular symptom is that attempts to send a message over 1432 bytes in size over IPv4/UDP will cause the above error message and the message to be dropped. What's up with the IPv6 error message I do not know.
