About this network

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-20040701 and UK-GYRON-20060131 registered 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.
