I truly want to believe that, and I do appreciate the effort that Willam and Elan put into this. That said, I do near-daily diffs between changes made to http://completewhois.com/bogons/data/data-bgp-announced/announced_bogon-cidr-all.txt
The correct entry is obviously 220.127.116.11/13
133/8 is special case because APNIC does not import this data in their whois.
Completewhois collection system does separate whois query to nic.ad.jp for each individual /16 out of it to find which of the blocks are and are not allocated. There are issues when data is not received properly or when they change format; plus to that there is no 2nd way to correlate the data as for example between RIR whois and statistics data. JPNIC also at times does not respond so as a result of all this, I changed collection to run not once a day but once/week (this was done over year ago) and at times check data manually too. Last time this collection was run was run is Apr 15th 4am which produced the following _correct_ list of bogons for 133/8
(this special data is at http://www.completewhois.com/bogons/data/jp/):
However previous days the data looked like this:
18.104.22.168/16 22.214.171.124/30 126.96.36.199/30 188.8.131.52/30 ...
So in fact it was improperly listing first 4 ips of the each /16
(but not entire /16 as you printed). In actuallity its also exactly
the same bug just manifesting itself in different way due to how JPNIC collection is done.
Unless I'm mistaken this is new PI allocation done 2 days ago. So system worked as it should be removing it from the bogons list.
I'm just trying to get a complete (not constantly changing) list of bogons.
The list changes and collection are done everyday on purpose as completewhois system produced data not on IANA bogons which change infrequently but more specific bogon data based on RIR allocations,
i.e. it tries to catch and list portions of blocks that IANA allocated
to RIR but RIR has not yet allocated/assigned to end-user or ISP.
As RIRs make allocations basicly every business day, completewhois data is recollected to make sure it corresponds to most current data.
If you have further questions it maybe better to send them to me privately and when I'll try to respond and check on the differences if you find something significant.
Its also in my plans to write "bogon 2.0" system as I've learned quite a bit about how things should and should not be done in the last 2-3 years so 2nd time around should be much better (and I'm also better programmer as I switched from being operations network engineer who did some programming on side to operations monitoring & other tools programmer). When I get to this project (maybe over the summer), this will include user web interface to see exactly what changes were done each day and exactly why system added or removed particular block(s).
