I disagree... putting limits on the holder of space that prevents
them from breaking it up too rapidly (and thus creating BGP table
growth) is fairly easy. Putting limits on the buyer makes the
transfer market incredibly complex and confusing.<br>
<br>
For instance, a buyer who needs a /23 of space might see that
there's no /23s available but that there are two /24s available. Can
they acquire those /24s?<br>
<br>
Under existing policy the answer is "yes, if they can demonstrate
need for the /23 of space". Under the various proposed policies the
answer is "it depends". In some cases it might depend on whether or
not ARIN had originally allocated either or both of those as /24s.
In other cases it might depend on whether the two /24s come from the
same original block that ARIN had allocated. But in no case is the
answer simple.<br>
