Is your university among these? https://www.visualcapitalist.com/wp-content/uploads/2019/03/...

University of Delaware, per this: https://dnschecker.org/asn-whois-lookup.php?query=AS2

So, not on that map, but it was part of ARPANET by the time the TCP/IP protocol was introduced in 1983[0], per this map: https://www.historyofinformation.com/image.php?id=6456

I wonder why there's so many weird domains being hosted on AS2? https://dnslytics.com/bgp/as2 (scroll down to Top Domains)

They are probably not actually hosted on AS2. Bad actors can inject garbage into BGP AS paths, either accidentally or deliberately.

Bad actors aren’t blacklisted for repeatedly injecting garbage?

Maybe? Sometimes? It probably depends if what they're doing causes operational issues. BGP is primarily a trust based system. Many upstreams have filters to limit route announcements from their downstream / customer ASes, but at its core, it is trust based.

It’s hardly trust based if enforcement against those who break the trust is so sporadic.

Interesting

(Not the guy you replied to, but) it's not, unless I am missing it. ASN 2 is University of Delaware. You can search for yourself at whois.arin.net, just type a number in the search bar in the upper right.
