Hi Phil,

NBT name resolution is IPv4 only. Samba does work over IPv6, but NetBIOS name resolution is and always will be IPv4 only. It is a feature of the protocol not Samba.

Take a look at http://www.ipv6consultancy.com/ipv6blog/wp-content/uploads/sambaxp-2015-deploying-ipv6-only-samba-4-environments-v0_4.pdf and other presentations on the subject at http://www.ipv6consultancy.com/ipv6blog/?cat=4.

Subject: [Samba] IPv6?

I noticed that samba is listening on IPv6, so I became curious and wondered if I could actually use it, and so far, it looks like it isn't usable.

Running nbtstat -A fe80::216:3eff:fe6f:1f3a on Windows returns the stupid message that the address must be in the a.b.c.d format.  I then tried using nbtlookup from linux:

nmblookup -S -U '[fe80::216:3eff:fe6f:1f3a]' \* *<00>
Looking up status of
        DEVSERV2        <00> -         B <ACTIVE>

Why is it reporting the IPv4 address when I queried it with the IPv6 address?  It looks like nmbd is listening on IPv6, but does not or is not able to report an IPv6 address.
