About this network

AS-HODGSON-RUSS-NET, the network of Hodgson Russ LLP, a US law firm headquartered in Buffalo, New York.

What it's used for

• Corporate networking for the firm's offices: internal systems, document and case management, and the connectivity its attorneys and staff use.

Notable

• A small enterprise allocation (about 2,560 IPv4 addresses) belonging to a single professional firm. Not an ISP, and not hosting.
• Law firms run their own address space for the same reason accounting firms do: client confidentiality makes tightly controlled, self-operated networks attractive.

Interesting

• Despite the low AS number, this is not an early-internet allocation. The ARIN registration was created in 2009, meaning AS3576 was issued to its current holder long after the number space below 4000 was first used — a good example of why a low AS number alone proves nothing about a network's age.
