[routing-wg] some stats for proposal 2018-06

Hi,

I support the proposal and I'd like to add a 
**quick'n dirty** "impact analysis".


1) I took the 69178 [1] RIPE-NONAUTH route objects
and run them through RPKI validator* 3.

Which gives me 758 RPKI INVALID (669 ASN mismatch + 89 ML mismatch) objects.
These objects would be the once that get removed as per the proposal.

distribution by RPKI validity state:
  67904 UNKNOWN
    669 INVALID_ASN
    516 VALID
     89 INVALID_LENGTH


2) to estimate the impact of the route object deletion I then further categorize these 758 prefixes by
asking:
- Are they currently announced? (visible in RIS)
- Are they currently announced by the origin in the route object?
I only looked at exact matches - not less specifics.
(RIPEstat prefix-routing-consistency data call was used to answer these questions)

If one of these two questions is answered with "no", then I expect
the potential impact of the deletion to be smaller than the other once (where
both questions are answered with "yes").

Only 55 [3] objects (28 unique ASNs) are currently announced and match the origin in the route object.


We can analyze these 55 further by asking
"Are there IRR entries for them outside of RIPE-NONAUTH already?"
(didn't do that yet)


route6 stats
-------------
total route6 objects found in RIPE-NONAUTH: 1991 [2]
affected prefixes: 18 (12 ASN mismatch + 6 ML mismatch)

break down by RPKI validity state* (including INVALID reason):

   1879 UNKNOWN
     94 VALID
     12 INVALID_ASN
      6 INVALID_LENGTH


kind regards,
nusenu
