[NANOG] Multihoming for small frys?

Wed May 21 19:02:54 UTC 2008

Thanks for the info.  We needed larger than /22 anyways.

I am a bit surprised that they will hand out a small allocaiton for 
multihomers.  These days it's very easy to do.  And, could be a easy way to 
horde some v4.

Notice the caveats:

To qualify under the IPv4 Multi-homing policy, your organization must prove 
an intent to multi-home, demonstrate utilization for at least a /23-worth of 
IP addresses assigned by upstream providers, and provide 3-, 6-, and 
12-month utilization projections.

In addition, your organization must agree to use the requested IPv4 address 
space to renumber out of your current address space, and to return the 
original address space to your upstream provider(s) once the renumbering is 
complete. Additional space will not be allocated until this is completed. 
Organizations that qualify under this policy may also qualify and request 
space under ARIN's general IPv4 allocation policy.

Of course, this could be smoke and mirrors.  Not sure.
