About this network

LAGRANGE is operated by Lagrange Cloud Technologies Limited.

What it's used for

• The address space carries cloud and managed services, as indicated by the netnames LAGRANGE-CLOUD and LAGRANGE-MAN registered to Lagrange Cloud Technologies Limited.
• The AS announces 512 IPv4 addresses across 2 prefixes and 3 IPv6 prefixes, while maintaining 114 observed routing neighbours. This high neighbour-to-address ratio indicates a transit or peering-heavy role rather than a large-scale access network.
• Traffic from this AS consists of web and API endpoints, cloud workloads, and managed IT services for business clients, consistent with the operator's focus on cloud infrastructure and managed services in the United Kingdom.

Notable

• Registrants for both announced IPv4 prefixes agree with the AS holder, listing Lagrange Cloud Technologies Limited as the registrant for LAGRANGE-CLOUD and LAGRANGE-MAN.
• The address inventory is compact, consisting of two /24 IPv4 blocks and three IPv6 prefixes, which is typical for a specialized cloud provider rather than a mass-market ISP.
