Summary

Madison County New York

United States of America · AI-generated

government county rural us

MADISONCOUNTYNY-01 is operated by Madison County New York.

What it's used for

  • The space carries county government infrastructure, evidenced by the netname MCNY-1 and registrant Madison County New York.
  • The AS announces 256 IPv4 addresses within a single prefix (198.176.192.0/24) and maintains 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or large-scale access provider.

Notable

  • The RDAP registrant Madison County New York matches the AS holder name exactly, confirming direct ownership of the address space.
  • The address inventory consists of a single /24 block, which is typical for a municipal or county government entity managing its own internal IT and public services connectivity.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
