About this network

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 to Haynes 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 /17 covering 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.
