sahilisterSad that we don't have any RouteViews BGP collector here in India https://www.routeviews.org/routeviews/map/
Nick BuraglioNSRC at the University of Oregon is looking for Network Engineer and Peering Coordinator for the #RouteViews project. If you aren't familiar with RouteViews and you're a network engineer, it's worth checking out. https://www.routeviews.org/routeviews/
This is sure to be a fun gig with an absolutely fantastic group of folks doing interesting and impactful work. Things like this don't come up often so if you're interested, check it out here:

Extremely cool animation showing the absolute explosion of #IPv6 networking globally over the last 20 years, all based on #RouteViews data. https://youtu.be/tMyFRGGGWOQ
The Internet: IPv4 vs IPv6 (1m)
Doc Edward Morbius ⭕@alex A trick that I like to use for consolidating activity sources in logs is to look at the ASN.
You can get this by querying the Routeviews DNS server, using a reversed dotted-quad lookup. For example, using social.alexschroeder.ch:
$ host -t txt 237.50.209.178.asn.routeviews.org
237.50.209.178.asn.routeviews.org descriptive text "29691" "178.209.32.0" "19"
So, you're on ASN 29691, CIDR 178.209.32.0/19.
If you're seeing a large amount of non-organic traffic from a specific AS, CIDR block, or set of related CIDR blocks, you might choose to rate-limit, restrict, or block those entirely.

Since this is DNS-lookup-based, what I typically do for recording is to flood-query a large number of IPs first, to seed my cache (you are running a caching DNS server, right), then do the reporting run. It's still generally useful to run parallel queries to avoid blocking.
You can also grab and host the zone maps themselves, I believe, documented on the Routeviews site ... somewhere.

Doc Edward Morbius ❌@kensanata I've long found clustering by ASN & CIDR block to be far more revealing.
Reverse IP to CIDR & ASN lookup.
Crawl bots tend to work out of nonresidential contiguous IP space, though AWS and Tor modify that somewhat.
