government municipal south-carolina

GREENVILLECOUNTYSC is the autonomous system for Greenville County, the most populous county in South Carolina.

What it's used for

  • The address space carries municipal government traffic, evidenced by the reverse DNS record mail2.greenvillecounty.org within the announced prefixes.
  • The AS announces 768 IPv4 addresses across 2 prefixes (206.74.192.0/23 and 206.74.42.0/24) and maintains only 2 observed routing neighbours, a ratio consistent with a small, self-contained institutional network rather than a transit or access provider.
  • Traffic from this AS consists of internal county operations, including email services and administrative endpoints for the local government.

Notable

  • The RDAP registrants for both announced prefixes list Spirit Communications with the netname IAVE-4, which differs from the AS holder Greenville County; this indicates the address space was originally allocated to or leased from Spirit Communications.
  • The inventory is compact, consisting of one /23 and one /24 block, with no IPv6 prefixes announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-24, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 443 networks and 1,779 prefixes, as published 2026-10-25. 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.
