It appears that Starhub / AS 4657 has a number of misconfigurations in their RPKI ROA setup. Does anyone from APOPS have contacts there that can help?
Earlier Wednesday, Markus Weber from KPN and I compared notes on another mailing list regarding a recent step increase in invalid routes seen by our networks. Job Snijders thought it would be good to mention it to this list, too, so here it is:
Between two snapshots taken 24 hours apart, I noticed an increase of more than 1100 invalid prefixes (ipv4+ipv6) as received in as7018. On 11-Dec I had counted about 5300, and on 12-Dec it was up to almost 6500.
A time-series plot shows increases occurring just after 1200 UTC on 11-Dec, and again after 0900 UTC on 12-Dec. (Of course this timing depends on the schedule I have my RPs running and other factors.)
I noticed that many of the new invalids were ipv4 /23s and /24s originated by as55430 (Starhub in Singapore) under a VRP of 188.8.131.52/16-22;as55430, and ipv6 /48s also originated by as55430 under a VRP of 2406:3003::/32-38;as55430.
Markus had a more complete data set, and he saw the following increases in invalids originating in the following Starhub ASNs:
15 srcAS=28118 30 srcAS=9874 283 srcAS=55430 429 srcAS=4657
Does anyone here know folks at Starhub who can be educated, or see anything else in the data worth discussing here?
