Summary
Essentia Health
enterprise legacy
ESSENTIAHEALTH-3789 is registered to Essentia Health East, part of Essentia Health, an integrated non-profit health system serving Minnesota, Wisconsin, and North Dakota from its base in Duluth, Minnesota.
What it's used for
- Enterprise networking for a hospital and clinic system: hospitals, clinics, administrative sites, and the clinical applications behind them.
Notable
- Small announced footprint (about a thousand IPv4 addresses). Healthcare systems typically run an AS for multihomed reliability rather than for volume.
- This is institutional address space. Traffic is staff and clinical systems, not consumer eyeballs, and much of the estate sits behind the enterprise perimeter rather than on the public internet.

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: 442 networks and 1,771 prefixes, as published 2026-10-15. 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.
