AS53901 BWS-DR-IX-AS
Unclassified ARIN Enterprise
Summary
Board of Water Supply
government utility water enterprise
The AS handle BWS-DR-IX-AS is held by the Board of Water Supply.
What it's used for
- The address space carries the internal network of the Honolulu Board of Water Supply, a municipal utility responsible for water supply and sanitation services in Hawaii.
- The AS announces 512 IPv4 addresses within a single prefix (205.167.232.0/23) and maintains 2 observed neighbours, indicating a small, self-contained enterprise network rather than a transit or access provider.
- Traffic from this AS consists of internal corporate communications, operational technology for water infrastructure management, and administrative endpoints for the utility's staff and systems.
Notable
- The RDAP registrant for the announced prefix 205.167.232.0/23 is listed as "Board of Water Supply" with the netname BWS-HI, which aligns directly with the AS holder.
- The address inventory is compact, consisting of a single /23 block, which is typical for a municipal utility managing its own internal IT and OT networks without large-scale public address allocation.

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 2026-10-30, 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 1,848 prefixes, as published 2026-10-31. 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.
