pkg.freebsd.org via IPv6?

[h v]

Dear list,

it took me while to figure out that seemingly hanging 'pkg update' are
working flawless when called as 'pkg -4 update' - it seems

that pkg.freebsd.org is  not (always?) reachable via it's IPv6
address... is this a known problem ?

Example pings:

--- C U T ---

$ ping pkg.freebsd.org
