Who works in much, especially with the network, is often not around, and from time to launch a whois query. So you get the fastest out if a domain is still available, or whether they connected up properly, that is, went off on a server or not. Even as we learn more details about using the name server, and so on.
Such a whois query, you shall, on each NIC (Network Information Center) of the domain concerned in general. In the case of .de domain would be DENIC. However, there may well be some hurdles here until you reach the desired information, such as eisy realized.
There are, however, to start such a query without having to access the pages of the NICs, if you do not always know which NIC is currently responsible for the TLD one possibility. The solution lies in the so-called whios clients.
In Linux, there is a simple console program called “whois”, which can be installed. The call is then made directly to the console:
For Windows, there are also those clients. A brief inquiry to Google yielded similar results quickly. It should, however, said that the most NICs limit such queries to avoid too many are sold. The advantage of such clients is of course on hand. You have to not having trouble with any spelling or similar mechanisms and the client acknowledges hand the TLD also equal to the corresponding NIC.
Just because engineers originally thought it useful to make their private address books each queried, this practice does not have to be regarded as a central base component of the Internet by rights exploiters and law enforcement agencies. On the contrary, legality and appropriateness should be reviewed following the changed environment since 1978.
The data collection of the Whois lack of formal international foundations, they are in direct conflict with national legislation. The German data protection, for example, prohibits direct the collection of data, since no specific purpose exists. By bringing together in a central database and the public, unrestricted access to mention.
Although the demand to indicate the specific, achievable directly contact constitutes the core idea of Whois Proxy services are allowed almost everywhere. A proxy service is instead of the correct contact person in the whois, but gives the correct data at the request in individual cases and with the consent of the person concerned out. The simultaneous demand for usable directly contact the admission of proxy services is inconsistent and so does a Whois from the outset nonsensical.
The data in the WHOIS are worthless for the purpose of prosecution. Just do not report their heavy criminals Internet resources just under her real name, they typically use stolen credit cards and Identiäten. It is the thousands of network operators can not be expected to carry out identification measures that resist organized crime. It is also naive to assume that the criminals do not occur even as an ISP or company Registar below deck. The law enforcement authorities on the AtLarge summit in Mexico dargeleget clear that they need to go the full way from the IANA, the registries on the reseller chain to the end-users (for domains and IPs) for reliable information. Whois helps them only at the initial orientation and the determination of the Registry.
The data in the WHOIS can not be used for law enforcement. In the current crime easier Whois databases are often the only data source that könnnen based investigators, because the crime of fraud in value from a few tens euro does not justify a preliminary identification of all users. For light crime, the introduction of a system such as Whois in most countries would be simply unconstitutional.
The data collection of the Whois quickly become obsolete. The transfer of the personal information of network participants in external databases creates a divergence between the real address data and the initial scale copy. The effort to keep this information always correct is quite impressive when you would not demand immediate direct public access to the CRM-system or provider of timely full copy of the data. Such public insight into the business data corporation is only being considered in any other industry.
In subdomains and end address is being denied in practice, the registration of the necessary information or actually performed only sporadically. Formally, the non-registration to protect the customer is not permitted. This invalidates much of the uses of Whois.
