Summary
Lone Star College System
education college network
NHMCCD is the autonomous system for Lone Star College System District.
What it's used for
- The address space carries educational network traffic, evidenced by netnames such as
LONE-STAR-COLLEGEandNORTH-HARRIS-MONTGOMERY-COMMUNITY-COLLEGE. - The system announces 3328 IPv4 addresses across 8 prefixes with only 2 observed neighbours, a ratio typical of an access or eyeball network serving a specific institution rather than a transit provider.
Notable
- All registrants in the evidence pack are listed as
Lone Star College System District, which aligns perfectly with the AS holder name. - The address inventory consists of eight distinct IPv4 blocks, including /23 and /24 prefixes, with no IPv6 prefixes currently in the inventory.

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 2026-11-01, 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: 447 networks and 1,843 prefixes, as published 2026-11-02. 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.
