Summary

Harris County Emergency Corps

United States of America · AI-generated

government emergency public-safety houston

The AS handle HCEC-HOUSTON-PRIMARY is held by Harris County Emergency Corps.

What it's used for

  • The address space carries the HCEC-PUBLIC-SAFETY-NETWORK netname, indicating infrastructure for emergency medical services and public safety operations.
  • The AS announces 4096 IPv4 addresses within a single /20 prefix (142.54.208.0/20) and maintains 3 observed neighbours, a ratio consistent with a dedicated internal network rather than a transit or large-scale access provider.
  • Traffic from this AS consists of internal communications, dispatch systems, and operational data for the county's pre-hospital care and emergency response units.

Notable

  • The RDAP registrant Harris County Emergency Corps and netname HCEC-PUBLIC-SAFETY-NETWORK align directly with the AS holder and its operational purpose.
  • The address inventory is a single contiguous /20 block, typical for a specific organizational unit requiring a defined range for internal segmentation.

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.
