government internal ny us

The AS handle SUFFOLK-COUNTY-GOVERNMENT is held by Suffolk County Government, the administrative body for Suffolk County, New York.

What it's used for

  • The address space carries internal government operations, evidenced by netnames NYSUFF-CIVSERV (Suffolk County Department of Civil Service) and NYSUFF (Suffolk County Department of Health).
  • The network announces 768 IPv4 addresses across 2 prefixes with only 2 observed neighbours, indicating a small, self-contained internal estate rather than a transit or access provider.
  • Traffic from this AS consists of internal administrative, health, and civil service data for the county government, not public subscriber or commercial traffic.

Notable

  • Registrants align with the announcer, specifically identifying the Suffolk County Department of Civil Service and the Suffolk County Department of Health.
  • The inventory is finely subdivided into two distinct prefixes, reflecting site-by-site or departmental segmentation within the county's internal network.

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