Summary

Alaska Native Medical Center

United States of America · AI-generated

healthcare business hospital

ALASK-15 is operated by Alaska Native Medical Center.

What it's used for

  • The address space carries internal network traffic for the medical center, evidenced by the netname ANTHC and reverse DNS records pointing to anthc.org.
  • The AS announces 1024 IPv4 addresses within a single /22 prefix (199.59.216.0/22) and maintains 2 observed neighbours, a ratio consistent with a standalone corporate or institutional site rather than a transit provider.

Notable

  • The RDAP registrant Alaska Native Medical Center aligns directly with the AS holder and the reverse DNS domain anthc.org.
  • Secondary sources indicate the facility was acquired by the Alaska Native Tribal Health Consortium, which now holds title to the hospital campus in Anchorage.
  • The inventory consists of a single contiguous IPv4 block with no announced IPv6 prefixes, reflecting a focused internal estate for a 182-bed hospital.

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: 448 networks and 1,851 prefixes, as published 2026-11-04. 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.
