United Kingdom · AI-generated

datacenter transit hosting uk

DIGITAL-REALTY-UK is operated by Digital Realty (UK) Limited.

What it's used for

  • The address space carries data center and hosting infrastructure, evidenced by netnames UK-CHEETAH-20150424 and UK-CHEETAH-20160923 registered to Digital Realty EMEA, alongside leased blocks for Bell Microsystems Ltd and SherWeb inc.
  • The AS announces 36,096 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, while maintaining 78 observed routing neighbours; this high neighbour-to-address ratio indicates a transit or interconnection role rather than a pure access network.
  • Traffic from this AS consists of data center tenants, cloud services, and interconnection partners leveraging Digital Realty's global ecosystem for connectivity and hosting.

Notable

  • Registrants for the largest prefixes align with the announcer, specifically Digital Realty (UK) Limited and Digital Realty EMEA, while smaller prefixes are registered to third parties like Bell Microsystems Ltd and SherWeb inc.
  • The address inventory is a mix of large Digital Realty blocks and smaller leased or acquired prefixes, including 83.142.64.0/21 and 74.115.206.0/24, reflecting a diverse portfolio of data center and hosting assets.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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: 442 networks and 1,778 prefixes, as published 2026-10-20. 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.
