Just some brainstorming here...
It should always be possible to populate the local /etc/hosts file as
an override to DNS with a local unique name. And then use that local
name in the config file.
Example /etc/hosts:
93.184.216.34 foo.example.com foo
2606:2800:220:1:248:1893:25c8:1946 foo.example.com foo
Example ssh config:
Host shortname realname.example.com
HostKeyAlias realname.example.com
Hostname foo
Use like:
ssh shortname
ssh realname.example.com
I tested this just now and on a host with IPv6 connectivity it used
the IPv6 address. The same configuration on a host with only IPv4
connectivity used the IPv4 address.
It's perhaps not the simplest of configurations but it did seem to fit
the criteria. The way to get both an IPv4 and an IPv6 address
available to Hostname. By stitching it through the /etc/hosts file.
WDYT?
Bob
