Summary

South Jersey Radiology Associates

United States of America · AI-generated

business healthcare corporate

54472 is held by South Jersey Radiology Associates, P.A.

What it's used for

  • The space carries a single /24 block with netname CCCH3-4 and registrant Comcast Cable Communications, LLC, indicating the address space is provisioned by a cable ISP rather than owned by the radiology group.
  • The AS announces 256 IPv4 addresses across 1 prefix with 1 observed neighbour, a ratio consistent with a small, dedicated corporate or branch network rather than a transit or large-scale access provider.
  • Traffic from this AS consists of office and clinical site connectivity for a medical imaging provider operating 16 locations in South Jersey, carrying administrative, patient portal, and diagnostic imaging data.

Notable

  • The RDAP registrant Comcast Cable Communications, LLC differs from the AS holder South Jersey Radiology Associates, P.A., reflecting a leased or provisioned address block from a cable operator rather than direct ownership of the IP space.
  • The address inventory is minimal, consisting of a single /24 prefix with no IPv6 announcements, typical of a small private enterprise network.

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: 442 networks and 1,779 prefixes, as published 2026-10-24. 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.
