Summary

Encompass Health Corporation

United States of America · AI-generated

healthcare business corporate internal

HEALTHSOUTH is the autonomous system for Encompass Health Corporation.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname HEALTHSOUTH-CORPORATION and registrant Encompass Health Corporation for both announced prefixes.
  • The AS announces 768 IPv4 addresses across 2 prefixes with only 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate communications, administrative systems, and clinical data flows for the company's nationwide network of rehabilitation hospitals and post-acute care facilities.

Notable

  • Registrants for both prefixes match the announcer, with Encompass Health Corporation listed as the registrant for 208.68.216.0/23 and 208.68.218.0/24.
  • The operator was formerly known as HealthSouth Corporation and rebranded to Encompass Health Corporation in 2018 to reflect its expanded scope of inpatient rehabilitation and post-acute healthcare services.
  • The inventory consists of two contiguous IPv4 blocks totaling 768 addresses, with no IPv6 prefixes announced, reflecting a legacy IPv4-only corporate 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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
