Summary
Community High School District 99
education k12 network us
CSD99 is the autonomous system for Community High School District 99, a public school district in Illinois.
What it's used for
- The space carries static IP addresses for district infrastructure, as indicated by reverse DNS entries like
static-66-158-46-128-csd99.organdst-66-158-47-126-wdsd7.org. - The AS announces 512 IPv4 addresses across 1 prefix with 1 observed neighbour, a ratio typical of a small, self-contained institutional network rather than a transit or large access provider.
Notable
- The RDAP registrant for the announced prefix is Illinois Century Network, which differs from the AS holder name, suggesting the address space may be leased or historically associated with a different entity.
- The address inventory consists of a single /23 block (66.158.46.0/23), providing a compact and manageable range for the district's connectivity needs.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
1 upstream, 0 downstream and 1 adjacent networks observed; most-used upstreams first.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-17, 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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
