Summary

Lone Star College System

United States of America · AI-generated

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-COLLEGE and NORTH-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.

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.
