business medical association us

AS54583 is held by American College of Surgeons.

What it's used for

  • The address space carries corporate infrastructure for a professional medical association, with one prefix registered under the netname ACS and two under COGENT-A.
  • The AS announces 768 IPv4 addresses across 3 prefixes and maintains 3 observed neighbours, indicating a small-scale internal network rather than a transit or access provider.
  • Traffic from this AS consists of office workers, administrative staff, and web/API endpoints associated with the American College of Surgeons' operations.

Notable

  • Registrants are mixed: Cogent Communications, LLC holds the two 38.x prefixes, while American College of Surgeons holds the 198.22.195.0/24 prefix.
  • The address inventory is small and fragmented, with two prefixes leased from Cogent and one directly registered to the organization.

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: 454 networks and 1,852 prefixes, as published 2026-11-08. 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.
