So it is not asking just a /16 but also asking for reservation of a /12.
Pretty big space.
And in the list of reasons, I mainly read that it is "sufficiently large",
but not much about why it needs to be this big. Why would a smaller
allocation not be sufficient?
Well, to keep it short, the WG felt that /16 is the "right size", and that if
the growth of LISP would be so important as to need a bigger space would be
nice to have it contiguous (so implementations can just change the prefix
length).
