Maybe I'm just not in the know on this but if these prefixes/ASes shouldn't be seen on the internet, shouldn't there be more of a public flogging to remove them?

Been there. Done that. See from 2003:
http://www.nanog.org/meetings/nanog27/presentations/hank.pdf

I had been doing this for over a decade and gave up a few years ago. Bottom line: No one gives a sh*t. Consider it all part of the background noise the Internet generates.

This one seems to be an error. 128.0.80/21 appears to have been allocated on 5 October, nine days before the report was generated.

The report is not 100% accurate. Some of the resources listed do appear to be used without being registered but not all of them.

Hi Leo,

Leo Vegoda said the following on 18/10/11 00:31 :

128.0.87.0/24 30977 JSC "Yugra-Telecom"

This one seems to be an error. 128.0.80/21 appears to have been allocated on 5 October, nine days before the report was generated.

The report is as good as what is in the RIR allocation databases, as I
grab those from the RIR public listings about 2 hours before the report
is run. So if it was allocated, it wasn't listed in the file that I pick
up. I'll investigate why.

The report is not 100% accurate. Some of the resources listed do appear to be used without being registered but not all of them.

It is as accurate as the data I have access to. :wink: But I'd be delighted
to hear suggestions for improvements.

You could try using http://bgp.potaroo.net/stats/nro/status.joint.txt

I use this as the basis of the bogon listing on the CIDR Report and I don't seem to be pickling up these false positives.
