Summary

Children's Hospital & Health System

United States of America · AI-generated

healthcare business enterprise

CHHS-1 is the AS handle for Children's Hospital & Health System, Inc.

What it's used for

  • The address space is registered under the netname CHHS-1 with the registrant Children's Hospital & Health System, Inc.; Network Support, indicating a dedicated corporate network for the healthcare provider.
  • The AS announces a single IPv4 prefix, 208.84.184.0/22, comprising 1024 addresses, with 0 IPv6 prefixes.
  • With only 2 observed neighbours, the low neighbour count relative to the address block suggests an internal corporate estate or site-specific network rather than a transit or large-scale access provider.

Notable

  • The RDAP registrant Children's Hospital & Health System, Inc.; Network Support aligns directly with the AS holder, confirming consistent ownership.
  • The address inventory consists of a single contiguous /22 block, which is typical for a large enterprise or hospital system managing its own internal infrastructure.

Reputation

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: 449 networks and 1,846 prefixes, as published 2026-11-02. 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.
