Summary

ProMedica Senior Care

United States of America · AI-generated

healthcare business corporate

MANOR-CARE is operated by ProMedica Senior Care.

What it's used for

  • The address space carries corporate infrastructure for a major US provider of short-term post-acute and long-term care, as indicated by the netname MANORCARE and registrant HCR Manorcare.
  • The AS announces 1024 IPv4 addresses within a single /22 prefix (208.78.12.0/22) and maintains only 1 observed neighbour, a ratio that indicates an internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of internal communications, administrative systems, and clinical data exchange for the organization's nationwide network of skilled nursing and rehabilitation centers.

Notable

  • The RDAP registrant HCR Manorcare and netname MANORCARE align with the AS handle MANOR-CARE, reflecting the organization's historical branding.
  • HCR ManorCare was acquired by ProMedica Health System and subsequently rebranded as ProMedica Senior Care, a transition that explains the persistence of the "ManorCare" identifiers in the registry data.
  • The inventory consists of a single contiguous IPv4 block with no announced IPv6 prefixes, typical of a legacy corporate allocation.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
