Summary

Sky Lakes Medical Center

United States of America · AI-generated

hospital business static us

The AS handle SKY-LAKES-MEDICAL-CENTER is held by Sky Lakes Medical Center, Inc.

What it's used for

  • The address space carries static infrastructure for the hospital, evidenced by reverse DNS entries such as 205-153-204-128.dia.static.skylakes.org and the netname SLMC.
  • The AS announces 512 IPv4 addresses within a single prefix (205.153.204.0/23) and maintains only 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.

Notable

  • The RDAP registrant Sky Lakes Medical Center, Inc. matches the AS holder, confirming direct ownership of the address space.
  • Sky Lakes Medical Center is a 176-bed acute-care hospital in Klamath Falls, Oregon, formerly known as Merle West Medical Center.
  • The inventory consists of a single /23 block with no IPv6 prefixes, typical of a legacy corporate or institutional 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: 453 networks and 1,846 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.
