Summary

County of Saginaw

United States · AI-generated

government legacy

The network of a Michigan county government.

What it's used for

  • County connectivity. 256 addresses in one /24 with two observed BGP neighbours and no IPv6 announced.

Notable

  • The AS handle is ITSC, the county's information technology department rather than the county itself.
  • The netname is USSIG-0-53-186-64-24, which contains the block's own address written backwards: 64.186.53.0/24 reversed octet by octet, with the prefix length on the end.
  • Every sampled address answers positionally as sag64.saginawcounty.com.

Interesting

  • That reversed netname is a small artefact of how reverse DNS works. Addresses are written backwards in in-addr.arpa so that delegation runs from the general to the specific, and whoever generated this label was working from that form rather than from the address as people write it. Templates encode the habits of the system that produced them.
  • Two neighbours for a county. Counties run courts, jails, elections, health departments and land records, and the second path is there because the systems behind those addresses have statutory deadlines rather than service level agreements. Redundancy at this scale is a legal requirement wearing networking clothes.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-25, 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 2026-10-24. 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.
