About this network

Corporate ASN (INSTINET-AS) of Instinet, the New York-headquartered institutional agency broker and electronic-trading firm, today the execution services arm of Japan's Nomura Group.

What it's used for

• Financial-market networking: order routing, execution platforms, market-data feeds, and connectivity to exchanges, dark pools, and institutional clients.
• Announces a sizeable block of legacy IPv4 space supporting trading infrastructure and corporate systems across its global offices.

Notable

• This is finance-industry address space, not a service provider. Hosts here are trading systems and the private connectivity around them, and much of the network's real work happens over dedicated circuits and exchange cross-connects rather than the public internet.
• Instinet was an electronic trading venue long before "electronic trading" was the norm, which is why it appears this far down the AS-number space.

Interesting

• Nomura acquired Instinet in 2007 and runs it as an independent subsidiary, so the ASN and its handle have outlived several changes of ownership.
