AS3356 is an autonomous system operated by Lumen (Level 3). Type: Backbone / transit carrier.
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 backbone registered as LEVEL3. Level 3 Communications became part of CenturyLink, which now trades as Lumen.
Lumen (Level 3) mainly carries traffic between other networks. Websites rarely sit directly in a backbone AS; when they do, the address space is usually leased to a customer who has no AS number of their own.
The IP lookup resolves a domain, then shows the AS number, prefix and network name of each address. Addresses in AS3356 link back to this page.
AS3356 is registered to Lumen (Level 3). 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 Lumen (Level 3), but the server is run by whoever uses that address: a customer of Lumen (Level 3), or Lumen (Level 3)’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.
