AS51167 is an autonomous system operated by Contabo. Type: Hosting provider.
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.
Read by our server at the time shown. Nothing in this box is stored in the directory.
LiveSource: Team Cymru IP-to-ASN (DNS)Observed:
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 network of Contabo, a German hosting company known for virtual and dedicated servers.
The server is most likely rented from Contabo: shared hosting, a virtual server or a dedicated machine. On shared hosting many sites sit on one address, so the reverse DNS name usually names the hosting company’s server, not the site. It tells you who to contact about the machine, not who owns the domain.
The IP lookup resolves a domain, then shows the AS number, prefix and network name of each address. Addresses in AS51167 link back to this page.
AS51167 is registered to Contabo. 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 in Contabo’s network, so the machine is most likely rented from Contabo. The site itself is run by the customer, not by Contabo.
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.
