Force Inbound Connections to IPV6 only Is it possible to restrict all connections to an IPV6 address?
I've set
onlynet=ipv6
bind=::

But it seems that nodes are still attempting to connect to an IPV4 address (in addition to the IPV6 address).  Is there any way to prevent this?  I am seeing discover and addlocal both being set to the IPV6 address on startup.
Thanks!
onlynet only affects outbound connections.
If you only want inbound IPv4 connections (why?), you'll need to either:

Patch Bitcoin Core to bind to IPv6 addresses in IPV6_V6ONLY mode (see CConnman::BindListenPort in src/net.cpp)
Use some firewall rule on your system to prevent incoming IPv4 connections to it
Make sure you only have a publicly-reachable IPv6 address
