inetutils-ping6 is conceived to expect symbolic name resolution.
Should anyone disagree, iputils-ping6 is available with a different
default behaviour. Given compelling evidence, most design decisions
are available for discussion, but at present this is where this
project stands.

$ ping6 -n -c2 2001:910:1059:2::1

is your obvious choice. The switch '-n/--numeric' relaxes the default
behaviour.

Thank you for sharing your concerns.
