VSC-AS-VERMONT-STATE-COLLEGES is held by Vermont State Colleges.

What it's used for

  • The space carries the network infrastructure for the Vermont State Colleges system, as indicated by the netname VSC and registrant Vermont State Colleges.
  • The AS announces 65,536 IPv4 addresses across 1 prefix with 3 observed neighbours, a ratio consistent with an internal corporate estate for a multi-campus institution rather than a transit or access provider.
  • Traffic from this AS consists of office workers, students, and administrative endpoints across the system's campuses, including Vermont State University and the Community College of Vermont.

Notable

  • The registrant Vermont State Colleges agrees with the announcer, confirming the space is owned and operated by the institution.
  • The Vermont State Colleges System approved a rebrand combining Castleton University, Northern Vermont University, and Vermont Technical College into a single entity named Vermont State University.
  • The address inventory consists of a single /16 block, 155.42.0.0/16, which is finely subdivided to support the system's multiple campuses and administrative sites.

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: 442 networks and 1,779 prefixes, as published 2026-10-22. 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.
