The WhoisProxy for TLDs offered by InterNetX enables users to check the availability of domains quickly.

Table of Contents for this Site


The WhoisProxy for TLDs offered by InterNetX enables users to check the availability of domains quickly. Whois requests are carried out via the Linux console.


In order to use the WhoisProxy, we need to activate the service for the IP that will be used to access the WhoisProxy. As soon as it has been activated, you can use the WhoisProxy via the Linux console. You can order the WhoisProxy in the AutoDNS Customer Center, section Optional Services or contact our sales department ( or our domain support (

Adding, changing or removing IP addresses to the WhoisProxy

If you would like to add a new IP address to the WhoisProxy, please contact Sales ( To change an existing IP address that is used to connect to the WhoisProxy or to remove an existing IP address from the WhoisProxy please, contact Domain Services (


We place restrictions on the number of permitted Whois requests. If you would like to extend this limit, please contact our sales team ( In addition, the registries also restrict requests - the number of permitted requests therefore varies greatly from registry to registry.
When placing your order, you can choose a percentual threshold value for the Whois requests and set an email address. As soon as this Whois threshold value has been reached or respectively exceeded, you will be informed by email. This ensures that you can increase the Whois request limit in time if needed.
When implementing the Whois proxy, keep in mind the 3 queries per second per source IP restriction.

Specialties of the Whois Client for MacOS and certain Linux distributions

The MacOS Whois Client treats the queries differently, and certain Linux distributions may also be affected.

In some cases it is therefore necessary to enclose the query parameters in quotation marks:

whois -h " +no_header"


The WhoisProxy can be reached via the hostname In the request the hostname is entered after "-h".



Lists all supported TLDs.

whois -h tld


Displays the domain status (= domain availability check).

whois -h

full check

Displays all Whois results for the request. The results that are displayed depend on the type of registry (thin or thick) and on the data that the registry makes available (= full check).

whois -h full


Shows the domain status for several TLDs.

whois -h multi domain1,domain2 de,com,net
whois -h multi,,


Displays the domain claim data (in XML).

whois -h claim


Displays a list of the suported cmmands and parameters.

whois -h help




The query is only sent to the first responsible Whois server.



Specify the period of time until timeout (in seconds, default is 5 seconds).



The additional status values premium, claim und premium_claim are returned. Available for the commands "check" and "multi".



Displays the price class which is used to determine for how much the domain can be registered for.


whois -h claim

Returns the domain claim data (in XML).



Supresses the header display.

Domain Status

The domain availability checks (command "check" and "multi") check the availability of a domain. The following statuses of the domain can be returned. 

freeThe domain is available for registration or not listed in the registry's Whois database.

The domain is already registered. You can not register the domain but it may be possible to transfer the domain, if the registry supports this.

invalidThe domain name is not valid. Please check if the name consists of valid characters.
invalid and/or unsupported top-level-domainThe TLD is not valid or not supported

Un unexpected technical error has occurred which prevents the WhoisProxy from displaying a result.

timeoutThe Whois server did not respond within a certain amount of time.
remote request limit exceededThe maximum number of requests permitted by the registry has been reached or exceeded.
reservedThe domain is reserved and cannot be registered.
pending_deleteThe domain is in the deletion process and can not be registered at this time
claimThe domain is available but there is a trademark present in the Trademark Clearinghouse for the name and the TLD is currently in the Sunrise Claims Period.

This is a premium domain which can only be queried with the "+v2" parameter. The ordering process is specified by the registry.

premium_claimThe following statuses apply: "premium" and "claim".
marketThe domain is offered for sale.
