KLEIN-ISD is the autonomous system for Klein Independent School District.
What it's used for
- The address space carries the district's internal network infrastructure, with netnames including
NET-CCF-0-131-239-0-0-24,KLEIN-ISD-01, andNTTA-198-170. - The AS announces 768 IPv4 addresses across 3 prefixes and maintains 2 observed neighbours, a ratio consistent with a single-site or small multi-site institutional network rather than a transit or access provider.
- Traffic from this AS consists of staff, student, and administrative endpoints within the district's schools and administrative offices in Harris County, Texas.
Notable
- Registrants for the first two prefixes are Klein Independent School District, while the third prefix
198.170.192.0/24lists NTT America, Inc. and VIPAR as registrants. - The address inventory is small and subdivided into three /24 blocks, typical of an internal corporate or institutional estate.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-08, 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: 455 networks and 1,854 prefixes, as published 2026-11-09. 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.
