Summary

Pagosa Springs Medical Center

United States of America · AI-generated

hospital critical-access rural healthcare

The AS handle USJHSD-AS is held by Pagosa Springs Medical Center.

What it's used for

  • The address space carries the network infrastructure for a critical access hospital, as indicated by the netname USJHSD-NET and the registrant identity.
  • The AS announces a single IPv4 prefix, 199.116.208.0/22, comprising 1024 addresses, with 0 IPv6 prefixes.
  • With only 1 observed neighbour, the low address-to-neighbour ratio indicates a small, isolated site network rather than a transit or large-scale access provider.

Notable

  • The RDAP registrant Pagosa Springs Medical Center matches the registry holder and the AS handle, confirming consistent ownership.
  • The address inventory consists of a single contiguous /22 block, typical for a small institutional network requiring a modest amount of public IP space.

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: 453 networks and 1,848 prefixes, as published 2026-11-12. 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.
