That's simply not true. Many ISPs will advertise another's netblocks for a mutual downstream. The client doesn't have enough IP space to qualify for PI space in any case unless they utilize a /21 to 80% while being multihomed. I don't see the logic behind refusing the customer a request of this sort. Daniel Golding Senior Network Engineer NetRail, Inc. On Wed, 5 Apr 2000, Jesper Skriver wrote:

We have a situation where we have a client who wants to be dual-homed for redundancy. They are not large enough to get addresses from ARIN. Given that they are wanting us to allow another provider to route a subset of one of our address blocks(5 /24's out of a /16). Looking for some recommendation/dangers and general policies in reference to this. Thanks for any input. If this is the incorrect list to post this on please let me know.
Refuse to do it, the customer must get PI addresses for this purpose.
