About this network

The AS handle is MASSIVEGRID and the holder is MassiveGRID Ltd.

What it's used for

• The address space carries cloud hosting infrastructure, evidenced by netnames such as UK-MASSIVEGRID-20110309 and NY-MASSIVEGRIDINC associated with registrants MASSIVEGRID LTD and MASSIVEGRID, INC.
• The AS announces 11,520 IPv4 addresses across 12 prefixes and 1 IPv6 prefix, while maintaining only 6 observed neighbours, a ratio indicative of a hosting provider rather than a transit carrier.
• Traffic from this AS consists of enterprise-grade cloud VPS, dedicated servers, and managed hosting endpoints, supporting workloads that require high-availability clustering and DDoS protection.

Notable

• Registrants largely align with the announcer, with MASSIVEGRID LTD listed for most UK prefixes and MASSIVEGRID, INC for the New York block, though one prefix (89.33.68.0/22) is registered to Lukasz Sobon trading as SC Media Adam i Lukasz Sobon Sp. J. under the netname PL-SCM-20051129.
• The address inventory is composed of multiple /22 blocks and a single /24, reflecting a fragmented but substantial allocation typical of a growing hosting provider.
