Summary

University of Vermont Medical Center

United States of America · AI-generated

healthcare business university hospital

THE-UNIVERSITY-OF-VERMONT-MEDICAL-CENTER-1 is operated by The University of Vermont Medical Center Inc.

What it's used for

  • The address space carries internal hospital and university infrastructure, evidenced by reverse DNS entries such as s37host254.uvmhealth.org and netnames like NETBLK-MCHV and MCHV1.
  • The AS announces 4864 IPv4 addresses across 7 prefixes with only 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or large-scale access provider.

Notable

  • Registrants for the majority of prefixes, including 192.240.32.0/21 and 192.240.40.0/22, are listed as The University of Vermont Medical Center Inc, aligning with the AS holder.
  • The facility was formerly known as Fletcher Allen Health Care before being renamed to reflect its affiliation with the University of Vermont.
  • The inventory consists of seven IPv4 prefixes with no IPv6 announcements, showing a purely IPv4-based internal estate.

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 1,784 prefixes, as published 2026-10-19. 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.
