f Has a ::f1d0:<zone>:<net>:<node> style host address
IO Incoming only (Node can not make outgoing IPv6 calls)
OO Outgoing only (Node can not accept incoming IPv6 calls)
INO4 No IPv4 (Node can not accept incoming IPv4 calls)
PO4 Prefers Out on 4 (Node can make outgoing IPv6 calls,
but is configured to try IPv4 first)
6DWN The IPv6 connectivity of this node is temporarely down.
DOWN This node is temporarely down for both IPv4 and IPv6
PM Prospective Member. The node has demonstrated IPv6
capability but is not listed or does not advertise an
IPv6 address in the Fidonet nodelist yet.
*1 IPv6 address: 2001:41d0:000a:1a3b:f1d0:2:5020:2992
Notes:
To make an IPv6 connection to a node connected via 6to4 tunneling
one may have to force the mailer into IPv6 (-6 option in binkd's
node config). If the destination address is a 6to4 tunnel address
(2002::/16) many OSs default to IPv4 if an IPv4 address is present.
