United States of America · AI-generated

healthcare business internal

The AS handle SPECT-19-AS is held by Spectrum Health.

What it's used for

  • The address space carries internal corporate traffic for a healthcare organization, evidenced by the consistent netname SPECTRUM-HEALTH across all prefixes.

  • Spectrum Health merged with Beaumont Health to form BHSH Health, which subsequently rebranded as Corewell Health.

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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
