Summary

Providence Hospital

United States of America · AI-generated

healthcare business internal

The AS handle PROVAK is held by Providence Hospital.

What it's used for

  • The address space carries internal hospital infrastructure, evidenced by the reverse DNS entry secureftp.provak.org and netnames PHS-170-173 and PHAKI.
  • The inventory consists of 768 IPv4 addresses across 3 prefixes, with only 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.

Notable

  • Registrants align with the announcer, listing Providence Health & Services for the 170.173.x.x blocks and Providence Hospital for the 204.80.136.0/24 block.
  • The address inventory is finely subdivided into three /24 blocks, consistent with site-by-site segmentation for a single corporate entity.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, 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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
