About this network

HYPERNEPH is Hyperneph Ltd, a London-based cloud storage and hosting company (registered address 91 Brick Lane).

What it's used for

A small hosting / cloud network. The AS announces 3–4 /24s (~768 addresses) but shows a disproportionately high ~69 observed BGP neighbours for that size, implying significant peering relative to its tiny address footprint. No PTRs resolved on the addresses sampled.

Notable

• Hyperneph Software Limited (a majority-owned subsidiary of Catenae Innovation PLC) reportedly ceased trading around September 2022, though the parent company remains registered as active at Companies House and the AS is still announced.
• The many peers on so little address space is unusual for pure hosting and suggests the AS is also used for interconnection at UK exchanges.
