AS12884 — DRW-INVESTMENTS-AS

AS12884 announces 3 IPv4 prefixes covering 1,024 addresses and 0 IPv6 prefixes.

About this network

A trading firm on 1,024 addresses, held across three jurisdictions and one transit provider's block.

What it's used for

• The network of a proprietary trading firm's UK arm. 1,024 addresses across three IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.

Notable

• The inventory is 45.95.92.0/23, 45.95.95.0/24 and 149.14.21.0/24.
• Netnames are IL-DRWISRAEL-20190709, DRW-INFRASTRUCTURE and COGENT-149-14-16.
• The IL- block is registered to the firm's Israeli entity; the third is registered to a transit provider.
• Nine addresses were sampled and none returned a name.

Interesting

• Three blocks, three different holders, one AS: a UK company announcing space registered to its Israeli sibling alongside a block belonging to its transit provider. Trading firms open offices wherever the exchanges are, and the address records follow the corporate structure rather than the network.
• COGENT-149-14-16 is provider-assigned space, still named and held by the provider. Announcing it from your own AS is ordinary, and it also means those addresses do not travel if the provider is dropped. Mixing owned and borrowed space in one AS is a decision about which parts of the network need to be portable.
• 1,024 addresses is tiny and the firm still runs its own autonomous system. For latency-sensitive trading the AS exists to control routing, not to hold addresses, and the interesting engineering is in paths that a public routing table never shows.
