[inet-ops] Cidr report here?

[Randy Bush]

as folk are censored by an fool from another non-ops-run list,
having this as one place to discuss the cidr and ris reports
would be good.

the real question is what can effectively be done to get
clueless crap out of the routing tables.  the s/n in bgp
approaches that of a mailing list.  but it may easier to
apply technology to the bgp universe; e.g., see discussion
on c-nsp of auto-drop of covered prefixes.  to get actual
discussion moving, my opinion is appended.

i proposed to rodney today, there are three types of prefix
pollution.
  o pure crap, such as that we see on top of the weekly
    report
  o someone traffic engineering
  o legitimate holes (someone moving from at&t's 12/8)

a hardcore <bleep> such as i might just filter them all

a friendlier type might just dump longer prefixes if they
had the same origin asn (the new part of the suggestion)

a southern californian might only dump a longer prefix
if it has the same next hop as the covering prefix
