Summary

Livingston Educational Service Agency

United States · AI-generated

education government legacy

LIVINGSTON-ESA is the Livingston Educational Service Agency, the intermediate school district for Livingston County, Michigan, based on West Grand River Avenue in Howell. Michigan's ESAs/ISDs provide shared services — including wide-area networking and internet access — to the local school districts in their county.

What it's used for

This is a single-purpose leaf network. RIS sees one prefix, 206.57.160.0/21, 2,048 addresses, and exactly one observed neighbour. One upstream and one block is the minimum viable BGP deployment: the ASN exists so the agency can keep its addressing while changing or adding providers, not because it routes anything for anybody else. There is no IPv6 in the RIS view.

The one thing worth reading carefully is the registrant. ARIN records 206.57.160.0/21 as WAYNENET, org Wayne County Regional Educational Service Agency — a different, much larger Michigan ISD. That mismatch between announcing party and registrant is the first thing an IP-leasing check trips on, and here it is benign: Michigan's regional education service agencies are peer public bodies that share network addressing and services, and a county ISD announcing space registered to a sibling agency is cooperation between school networks, not a lease to an unrelated third party.

Notable

Despite the low AS number, ARIN's record for AS11718 shows a registration date of March 2023 — this is a recycled ASN, freshly issued to the agency, and its number says nothing about the age of the network behind it.

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.

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.
