Send the following form to Hostmaster@internic.net & iana@isi.edu, changing the $NET_PREFIX to the network being returned.
(yes, the below is a different situation than the original poster)
And what exactly do you do if you have a small block (eg. /22) that you have zero use for anymore and want to get rid of but it is not allocated directly from the InterNIC but rather out of another provider's block (a /16 in this case)?
As one of the grim-reapers of address space I'd like to point out a change that should get placed into Phils RFC and an offer to the nanog community. hostmaster@internic.net is likely to be moot real soon now and Kims response that this should change to hostmaster@arin.net is a viable replacement is almost ok. However I'd point out that under the terms of the InterNic award, they were the NIC of first and last resort. I don't beleive this is the case with ARIN. Two, and perhaps of interest to members of this list, I'm collecting prefixes again for reclaimation. I've done the traditional /8 space twice and 192.0.0.0/8 once. Now I'm willing to track any/all prefixes that you beleive should be returned. I've already got a list of traditional /16s that folks think should be returned and some /24s as well. I'll even do this for small blocks as well. -- --bill
