Leasing it out is exactly the answer for your situation, since you keep the block and can pull it back when the term ends. A /22 will find takers, that size is in demand. Two things to sort out before you list: decide who handles abuse complaints during the lease, because your name stays on the registry object, and check the reputation history of the range so you are not surprised by an old blocklist entry. We listed idle space through an
IP Broker , which saved me from vetting counterparties myself. Honest caveat: money is steady but not life changing at that size, so set expectations with leadership early. Tip: agree in writing on how quickly the lessee has to act on complaints, because your registry contact is the one getting the mail.
