Summary

Digital Realty Netherlands

Netherlands · AI-generated

hosting datacenter colocation

DIGITAL-REALTY- is operated by Digital Realty Netherlands B.V.

What it's used for

  • The address space carries data center and colocation infrastructure, evidenced by netnames such as NL-CHEETAH-19930901 and NL-CHEETAH-20161024 registered to Digital Realty entities.
  • With 25,856 IPv4 addresses announced across 6 prefixes and 92 observed neighbours, the high neighbour count relative to the address inventory indicates a transit or interconnection role typical of a data center provider.
  • Traffic from this AS consists of enterprise colocation clients, cloud service endpoints, and interconnection traffic routed through Digital Realty's Amsterdam data centers.

Notable

  • Registrants for the largest prefixes (51.163.192.0/18, 51.163.160.0/19) align with the announcer, listing Digital Realty Netherlands B.V. and Digital Realty EMEA contacts.
  • Smaller prefixes show historical or third-party registrants, including NAYAX LTD for 185.159.235.0/24 and 195.184.227.0/24, and ENGINEERING for 185.60.177.0/24.
  • The operator formerly operated as Interxion in the Netherlands before being acquired by Digital Realty in March 2014 and rebranded.

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 1,784 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.
