BARDCOLLEGE is the autonomous system for Bard College, a private liberal arts college in Annandale-on-Hudson, New York.

What it's used for

  • The space carries campus infrastructure and student services, evidenced by netnames BARDNET-A, BARD1, and BARD2 and reverse DNS entries like bardS19-119-254.bard.edu, sloth.bard.edu, and stu234-254.bard.edu.
  • The AS announces 11,776 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small, self-contained access network rather than a transit provider.

Notable

  • Registrants for the primary prefixes (173.46.96.0/19, 192.76.239.0/24, 192.83.253.0/24) align with the announcer, listing Bard College and its network operations team.
  • Two prefixes (192.246.224.0/21 and 192.246.232.0/22) are registered to Cogent Communications, LLC, suggesting leased or historically allocated space now announced by the college.
  • The address inventory is a mix of a large /19 block and smaller /24 and /22 blocks, typical of a growing institutional network.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-08, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 455 networks and 1,854 prefixes, as published 2026-11-09. 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.
