Hi John,

This is part of the service one buys upon telling an ISP you want a
/24 for multihoming per ARIN NRPM Not a fresh, new or
dangerous concept, nor one that fails to work.

IIRC, there was an effort to prevent this once... ISPs that wouldn't
accept these /24 BGP announcements from their peers. But that
collapsed as its enforcers realized it was costing them business and
is, today, a historical footnote.

Where the block in question is from a legacy registration, what
contractual or legal obligation prevents the holder from making a
lawful assignment larger than /24, without a multihoming (or any
other) requirement? And in perpetuity?
