AS12007 — RAYASN

AS12007 announces 36 IPv4 prefixes covering 79,872 addresses and 0 IPv6 prefixes.

About this network

The corporate network of Raytheon, the US defence contractor now part of RTX.

What it's used for

• Internal enterprise networking for a defence and aerospace manufacturer, spread across its engineering and manufacturing sites.

Notable

• 66 IPv4 prefixes for 80,000 addresses, but only four observed BGP neighbours. A network chopped that finely with almost no external adjacency is an internal estate: the fragmentation reflects site-by-site segmentation, not a desire to be reachable.
• Every block is registered to RTX Corporation under RTX-RAY-BLK3 and RTX-NETBLK-RAY-BLK2. Raytheon merged with United Technologies in 2020 and the combined company renamed itself RTX in 2023, so the registry has been updated to the parent while the netnames still say RAY.
• No IPv6 announced at all, unusual for a network holding this much IPv4.

Interesting

• The bulk of the space sits in 128.13.0.0/16, one of the early class B assignments made before address space was rationed. Defence contractors were connected to the ARPANET-era internet from the beginning, and the allocation is a direct artefact of having been in the room that early.
