Summary

Houston Community College System

United States of America · AI-generated

education business us

The AS handle HCCS is operated by Houston Community College System.

What it's used for

  • The address space carries the institutional network for the college system, identified by the netname HCCS-NETWORK on the majority of prefixes.
  • The AS announces 42496 IPv4 addresses across 15 prefixes while maintaining only 2 observed neighbours, a ratio indicative of an internal corporate estate rather than a transit or access provider.

Notable

  • Registrants are split between HOUSTON COMMUNITY COLLEGE SYSTEM for the 67.226.0.0/16 range and NTT America, Inc.; VIPAR for the 198.64.8.0/21 and 198.64.32.0/20 blocks, suggesting the latter may be leased or historically allocated space.
  • The inventory consists of two distinct blocks: a 67.226.0.0/16 range and a smaller 198.64.0.0/16 allocation, with no IPv6 prefixes announced.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
