Summary

Roper St. Francis Healthcare

United States of America · AI-generated

healthcare business internal us

RSFH is the autonomous system for Roper St. Francis Healthcare.

What it's used for

  • The address space carries internal corporate traffic for a not-for-profit health system, evidenced by netnames RSFHNET-1 and RSFHNET-2 registered to Roper Saint Francis Healthcare.
  • The AS announces 512 IPv4 addresses across 2 prefixes with 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of office workers, clinical staff, and internal systems for a healthcare provider in Charleston, South Carolina.

Notable

  • Registrants for both prefixes (RSFHNET-1 and RSFHNET-2) match the AS holder, Roper Saint Francis Healthcare.
  • The address inventory is finely subdivided into two /24 blocks, consistent with site-by-site segmentation for a single corporate entity.

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.
