i agree.  and, this is also true of native enum.  that's why i proposed
"fax us a copy of your phone bill" as a way to prove block-ownership.  if
there is another, more effective way to prove block-ownership, i am
educable.

this i knew.

this works.

this doesn't work.

it works until your provider enters the picture.

in dns, as in e164, autonomy is hierarchical.  you can only do what your
parent allows.
