research education ipv6

What it's used for

  • The space carries a single IPv6 prefix, 2a0e:97c0:930::/44, with no announced IPv4 addresses.
  • With 1 IPv6 prefix and 9 observed neighbours, the ratio suggests a small-scale network with multiple upstream or peering relationships.
  • As an educational and research entity, the traffic consists of academic and research endpoints.

Notable

  • The registry holder is listed as KARTHOR Andrea Adapa, aligning with the AS name KARTHOR.
  • The address inventory consists solely of one IPv6 block, indicating a modern, IPv6-only deployment.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 448 networks and 1,849 prefixes, as published 2026-10-30. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
