Re: v6ops-addcon and longer than 64 bit prefixes

[Brian E Carpenter <brian.e.carpenter at gmail.com>]

/56 is a choice currently used by the registries. That doesn't
invalidate using /48, if you consider that to be a more interesting
allocation unit to consider. So I don't see a problem with
"(e.g. on a basis of /48)".
