Paul,

My experience from being on the customer end of this arrangement is that
it should work whether you assign the customer a /24 from your own
netblock or have them buy a /22 direct from ARIN. In either case the
customer would need a unique ASN from ARIN.

If I remember correctly, the only requirement your customer would have
in order to be entitled to buy a /22 from ARIN is that they be
multihomed. I believe the cost is on the order of $1500/yr. If they
don't want to pay so much, getting the IP space from you would be a
savings; plus, it would add to the stickiness of your relationship with
the customer (to leave you, they would have to renumber their network,
which is often a hurdle -- and the reason we chose to get IP space
direct from ARIN a few years ago).

I'm not aware of a way to make this work utilizing a private ASN, unless
you and the other ISP have some kind of peering relationship.

My 2 cents, hope it helps
