About this network

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.
