AS9121 is an autonomous system operated by Türk Telekom. Type: Internet access provider (ISP).
Names identify network operators so that lookups can be read. They do not imply partnership or endorsement, and nothing here ranks one network against another.
The number-to-holder mapping was read from the Team Cymru IP-to-ASN service, which mirrors the regional internet registries, on 2026-09-21. The type is our own classification.

The country shown for an AS number or an IP prefix is where it is registered, not where a server stands. Large networks announce the same addresses from many countries.
The main AS number of Türk Telekom, the incumbent fixed-line operator in Türkiye. The registry data still shows its earlier internet brand, TTNet.
Türk Telekom is an access provider. A website on one of its addresses is usually self-hosted on a business or home connection, or on the provider’s own hosting service. For a visitor’s address, it only tells you which provider the connection comes from.
The IP lookup resolves a domain, then shows the AS number, prefix and network name of each address. Addresses in AS9121 link back to this page.
AS9121 is registered to Türk Telekom. The live box on this page shows the name, registry and allocation date as the registry data gives them at the moment of the lookup.
The address is announced by Türk Telekom, but the server is run by whoever uses that address: a customer of Türk Telekom, or Türk Telekom’s own hosting service.
Resolve the domain to its A and AAAA records and look up each address. OrbitProbe’s IP lookup does both and shows the AS number, the announced prefix and the network name for every address.
No. It is the country in which the number is registered. Networks announce addresses from many locations, and anycast networks answer from whichever site is closest to the visitor.
