Unclassified ARIN
Summary
Haynes and Boone
business enterprise infrastructure
A law firm holding a full sixteen-bit block, announced in nine pieces that say nothing about any of them.
What it's used for
- A law firm's corporate network. 65,536 addresses across nine IPv4 prefixes, with four observed BGP neighbours and no IPv6 announced.
Notable
- Every prefix carries the same netname,
HBNET, registered toHaynes and Boone, L.L.P. - All nine sit inside
165.97: one/17, two/19s, two/20s and four/21s. - The nine pieces tile the range exactly, with the
/17covering the upper half on its own. - Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- The split is a strict binary decomposition: halve, halve again, and stop wherever a boundary was needed. The upper half never had to be divided, so it is still announced as one piece, while the lower half broke into eight. That asymmetry is the network's own history, visible from outside.
- Nine records, one netname, one registrant, no site codes and no ticket numbers. The registry confirms who owns the space and refuses to say anything further, which is unusual in a range full of operators who spell the city into every entry.
- A sixteen-bit block for a law firm is timing rather than scale. Professional services firms that connected early asked when the answers were still generous, and nobody has taken it back.
- Nothing answers a reverse lookup, which for a network holding privileged client work is the only sensible setting.

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 2026-10-22, 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 2026-10-23. 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.
