RIPE Region Analysis Summary ----------------------------
Prefixes being announced by RIPE Region ASes: 14040 Prefixes being announced from the RIPE address blocks: 10985
It is interesting to see that when looked from Europe AS3333(RIPE NCC) number of prefixes are 13540 while AS4777 is 10568.
RIPE Address Blocks 62/8, 193/8, 194/7, 212/7 and 217/8
missing two /8s 195/8 and 213/8 Allocated by RIPE NCC. But it looks you are counting them in the prefix! http://www.isi.edu/in-notes/iana/assignments/ipv4-address-space There few other allocations missing from iana doc. like 192 sapce 24.132 allocations. Number of prefixes announced from those ranges are few. Complete list can derived from.

No: 194/7 consists of 2 /8's: 194/8 and 195/8.

Probably because your upstreams are sending your more specific prefixes which they aren't announcing to the rest of the Internet? Any other theories?

Have the three RIRs sat down and carved up the historical 192 space allocations between themselves? If they have, then I can put the effort in to add them to my summary. If not, simply having the RIPE NCC ones is not that interesting (for me, anyhow)... I'd also like to see a similar "carve up" of former A and B space - probably not a too hard project, but will take someone to write the script and parse the results for any errors...

Searching through this I've found eight /16s from 192 space... Might make a negligible difference in the greater scheme of things. philip --
