You can bet when people start paying for addresses there gonna be pretty
pissed when they aren't fully routable.
Eric,
Ping sweeping will only give NSI/InterNIC a rough estimate of
current online use. A route could be down at the time of sweep on one
end, and on the other a single web box could be using 50 IPs. Changes
would deffinately be welcome in policy. Policing via an "are you awake"
really shouldn't be one of them.
Which is why I agree ping sweeps won't work. And of course, we all keep our SWIP data up to date. BTW, I would hazard a guess that most of the wasted IP space is in the academic community. Does anyone really believe that MIT uses 16 million addresses? And I bet Internic asks for engineering diagrams to review from the big boys whenever they go back for an allocation. Kim, do you folks? I have a university client with 1200 hosts on 4 subnets. Guess what they've got? A /16. % Utilization: 1.83% % Waste: 98.17% Folks thats 64334 addresses. And we try and jam clients in to blocks of 8 or 16 discrete addresses. Squatters rights I guess :) I've seriously thought of approaching them for their "quality" IP real estate which isn't in the swamp.
From a post earlier this week to NANOG:
BGP table version is 4043818, main routing table version 4043818 52606 network entries (146045/157874 paths) using <color><param>ffff,0000,0000</param>11039224</color> bytes of memory 12848 BGP path attribute entries using 1589828 bytes of memory 27663 BGP route-map cache entries using 442608 bytes of memory 0 BGP filter-list cache entries using 0 bytes of memory Dampening enabled. 245 history paths, 46 dampened paths Feel free to privately email me ( mailto:ekgermann@cctec.com )as to why if I can jam 128M+ into a backbone router for peering and from above a 53K routing table fits in about 11M, why all the NSP's complain about bloat in the table? Poor lookup algorithm? Input would be appreciated for design references. Mail me and let me know. I don't want to dampen the S/N ratio on NANOG anymore than I have to.
BTW I am one of those that constantly has to scrounge for IP space.

sdsu.edu has 2 /16 networks for 35,000 students faculty and staff. total usage on 146.244.0.0 is two machines. % utilization 0.00305 % waste 100% anyone else got a better example? j.

Yes. Folk such as Suzanne and Bill who, instead of blabbering their silliness all over the mailing lists, worked with the institutions who were not using their large allocations to recover *large* amounts of address space which was returned to the IANA. <sigh> randy

well, unlike suzanne and bill, sdsu tried to sell that net to the local community colleges...i dunno what the disposition is of that transaction, but sdsu still has the net... i guess they want to much $$$ for it. arent all the nets registered before 1995 being grandfathered in (thereby being exempt to the outlandish pricing structure arin plans to charge)? j.

I admit to being confused: has 145.244.0.0 been returned to the IANA or? mail# whois 146.244.0.0 San Diego State University (NET-SDSU-SUBNETS)
