This contradicts the statement above that the maximum allocation or
assignment is a /21, not a /24. Or is it intended that the initial
allocation or assignment is always a /24, but the recipient can later
ask for more, up to a /21, with appropriate justification?
Or is it worded that way so that if an applicant comes back for a second
(or subsequent) allocation/assignment under this section (for a second
discrete network?) they may receive no more than a /21 in total?
Also, if the allocation or assignment is a /24, no more and no less,
what is the point of the 2nd sentence that ARIN should use sparse
allocation? Is it so applicants taking a second dip will, if possible,
get a contiguous /24 each time?
