Are they really overlapping allotments or just a demonstration of reassignment? i.e. They have 214.0.0.0/8, and they've decided to document that 214.0.0.0/16 is reserved for some reason.

I seem to remember that they were exchanged for 49/8 and 50/8. Seems a bit odd that this was done, and I'd love to know what the technical or operational or political advantage was. Maybe the IANA folks can shed more light?

214/8 and 215/8 seem to have been allocated to the U.S. DoD in ca. 1998. There does seem to be a few sizeable announcements (which overlap a few not-so-sizable ones), but I have to wonder if anyone can explain the grounds on which they were allocated these two /8s, and which body did the allocation. Anyone?

Sean.

I could. Why does it matter?

Oh, openness, transparency, that sort of thing. Nothing really important.

The full RFC2050 justification for a /7's worth of space would be a mighty and wondrous thing to behold. Joe

Interop is the Networld+Interop conference show network. It used to be simply Interop. I don't remember what the largest peak count of addresses used at any one time have been, but I'm fairly certain that it has easily numbered into the thousands for most of the recent U.S. based shows. A team of people build a very sizable, temporary network to support each show. The addresses are used for vendor booths, classrooms, attendees and more test/research-oriented areas (e.g. the iLabs pavilion). Its change a bit since the earlier days, but there are still parts of the network that are quite interesting. If you ever have a chance, its worth learning about. As long as the show continues in this present form, I think their space (45/8) is still justified. Although it is probably worth questioning from time to time. John

I'm not sure the current discussion is timely. Do we really want to start a reclaiming effort of IP addresses? Addresses such as Apple's, HP's, IBM's and others were made long before RFC2050.

Well by the looks of things ARIN, RIPE and APNIC are working their way though about a /8 each every year or so. This means that Class C space (as such) is going to be used up in a year or two (only 220-223/8 is unallocated). There are still over 60 /8s unallocated after that which means we aren't going to run out for a few years. When the numbers for broadband start working however things could quickly get tight. Still it's a bit off when Defence Establishments have /8s and probally a minimal number of world visable networks while medium sized countries have less. A quick check shows that the following /8s have little or nothing of them advertised into the global routing table. Of course there are probally a few others that have the /8 ad and almost no actual use. 006/8 Army Information Systems Center 008/8 Bolt Beranek and Newman Inc. 011/8 DoD Intel Information Systems 019/8 Ford Motor Company 021/8 DDN-RVN 022/8 Defense Information Systems Agency 025/8 Royal Signals and Radar Establishment 026/8 Defense Information Systems Agency 028/8 DSI-North 029/8 Defense Information Systems Agency 030/8 Defense Information Systems Agency 034/8 Halliburton Company 045/8 Interop Show Network 046/8 Bolt Beranek and Newman Inc. 048/8 Prudential Securities Inc. 051/8 Deparment of Social Security of UK 052/8 E.I. duPont de Nemours and Co., Inc. 054/8 Merck and Co., Inc. 056/8 U.S. Postal Service 215/8 US-DOD -- Simon Lyall. | Newsmaster | Work: simon.lyall@ihug.co.nz Senior Network/System Admin | Postmaster | Home: simon@darkmere.gen.nz ihug, Auckland, NZ | Asst Doorman | Web: http://www.darkmere.gen.nz

This space is clearly not justified - there are not, and have never been a million hosts at Interop. A /16 or so, would be far more appropriate. One might think that this would be an easy target for ARIN to reclaim, as the folks involved with the Interop show network, are uniformly clueful and there are few renumbering burdens. - Daniel Golding
