Summary

MassiveGRID

United Kingdom · AI-generated

hosting cloud vps dedicated

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.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 443 networks and 1,784 prefixes, as published 2026-10-19. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
