Choice of IP protocol version
Since IPV6 is increasingly the default protocol version for dns resolution (which is good), it could be great to be able to choose the preferred IP version for ssh connections.
My home desktop is indeed behind my provider's box (which doesn't support ipv6 port redirection), and I don't want it to be accessible from a public address so I still prefer ipv4 access right now.
I thought it could be great to be able to choose IP protocol version for specific hosts.
Anyway, thanks for that wonderful app.
