Summary

LHC Group

United States of America · AI-generated

healthcare business corporate

The AS handle LHC-GROUP is held by LHC Group, a healthcare provider specializing in hospice, home care, and facility-based services.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname LG-263 for the prefix 23.90.73.0/24 and the registrant LHC Group.
  • The second prefix, 69.1.165.0/24, has the netname LCG-LUS-CUST-GLOBALREACH-69-1-164M23 and is registered to Global Reach, indicating leased or third-party space.
  • With 512 IPv4 addresses announced across 2 prefixes and only 3 observed neighbours, the low neighbour count relative to the address inventory suggests an internal corporate estate or a small business network rather than a transit or large-scale access provider.

Notable

  • Registrants do not fully agree with the announcer; while one prefix is registered to LHC Group, the other is registered to Global Reach.
  • The address inventory is small and subdivided into two distinct /24 blocks, one of which appears to be external or leased space based on the differing registrant.

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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
