A very common noping use case for me is to check when a server comes up after reboot. For that I want to check both, IPv4 and IPv6 addresses of the same host, i.e. for the same hostname.

Currently I do this like this:

noping $(host someserver.example.org | sed -e 's/^.* address //')

It would be nice if noping would have an option to ping all IP addresses a hostname resolves, too, especially A and AAAA records. I suggest to use -5 as it is between -4 and -6, but -a or -A would be fine as well. Would then look like this:

noping -5 someserver.example.org

I guess oping itself (which I nearly never use) should get the same option, too.
