Unclassified ARIN
Summary
U.S. Department of Commerce, HQ and ITA
government enterprise internal
HCHBNET is operated by the U.S. Department of Commerce, HQ and ITA.
What it's used for
- The address space carries internal government infrastructure, evidenced by the consistent netname
ITA-Bacross all announced IPv4 prefixes. - The AS announces 65,280 IPv4 addresses and 12 IPv6 prefixes, with only 2 observed neighbours, indicating a self-contained internal network rather than a transit or access provider.
Notable
- All registrants for the largest prefixes are listed as "U.S. Department of Commerce, HQ and ITA", matching the AS holder exactly.
- The address inventory consists of eight IPv4 prefixes within the 170.110.0.0/17 block and ten IPv6 prefixes under 2610:20::/40, reflecting a finely subdivided corporate 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 2026-10-20, 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: 442 networks and 1,779 prefixes, as published 2026-10-21. 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.
