Summary
NTT Global Data Centers EMEA UK
hosting datacenter ntt uk
The AS handle GYRON is held by NTT Global Data Centers EMEA UK Ltd.
What it's used for
- The address space carries data center and hosting infrastructure, evidenced by netnames such as
UK-GYRON-20040701andUK-GYRON-20060131registered to NTT Global Data Centers EMEA UK Ltd. - With 34,560 IPv4 addresses announced across 10 prefixes and 75 observed neighbours, the ratio suggests a hosting or transit provider role rather than a pure access network.
Notable
- Registrants for the majority of prefixes align with the announcer, specifically NTT Global Data Centers EMEA UK Ltd., though smaller blocks are registered to Sharpstack Hosting Ltd, Sitebulb, and VM Linux Ltd.
- The operator was formerly known as Gyrion, a UK-based data center provider that was acquired by NTT Global Data Centers, resulting in the current registry name.
- The inventory consists of several /19 and /20 blocks alongside smaller /23 and /24 prefixes, indicating a consolidated corporate estate with some legacy or third-party allocations.

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 1,771 prefixes, as published 2026-10-15. 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.
