What is the WHOIS internet protocol service?

WHOIS, which comes from the English ‘Who Is’, consists of a transmission protocol that works with the request and response modality,  acting as a huge database where a high percentage of all information related to domain registrars is stored. , allows us to know the owner of a domain name or an IP address on the Internet, it should be noted that until a while ago, all the information stored in WHOIS was available to the general public.

In addition, it is a completely free service for those who show interest in knowing the data of the different domain owners, however, things have changed a bit, this as a result of the setting of the General Regulation for Data Protection exactly in 2018, even so, WHOIS continues to be the tool par excellence for domain registrars due to the simple way in which we can use it in the updated version of Windows, so we recommend you continue reading the article in order to to find out other interesting details related to this service.

What can we use the service provided by WHOIS for?

As we mentioned before, as it is a huge database, it contains information that it manages publicly, so all those interested in knowing the data and information about domain name owners can fully use it for their purposes, since It allows to locate both the name and the contact information of the operator of a domain name of a website, additionally it can be given other interesting uses, let’s see some of them.

Describe the availability of a domain name

This feature allows us to determine if a particular domain username is available for our use or is already in use.

Provides domain owner information

To find information related to those responsible for a domain name, we simply have to place the name in the corresponding section in WHOIS and we will have everything we need to know, such as their real identity, contact information and even their tax address.

Solve technical problems

Solving technical problems that may arise is also one of the interesting functions of this protocol service that helps us in many ways, as it allows us to communicate with network administrators .

Claim your copyright

Through the use of this , you can also contact the owner or owner of the domain in relation to issues regarding the protection and effective exercise of intellectual property rights.

What are the requirements I must meet to use WHOIS?

Any person or company that is interested in registering a domain name must provide technical and contact information that will be stored in the WHOIS database, when the domain name has been registered and after 7 days, all the WHOIS data that corresponds, which is why it must meet the following requirements.


The registered data connects people or companies with domain names , this is the reason why accurate and true contact data must be provided, if, on the contrary, we provide false data, we do not place them or do not answer any query related to the sincerity of the data within the fifteen days that we are given for consultation, the domain name could be suspended and even cancelled, although one program has nothing to do with the other, making a WHOIS query is very similar to the system of Access queries that is the same question-by-answer modality.

What are the types of data that WHOIS provides us?

We already know that the General Data Protection Regulation imposes some limits regarding the type of information and data that the WHOIS protocol can provide, however, in each query we make we can obtain information about the domain name, administrator ID, name of the registrar, data about DNS used, URL of the registrar, name and email address of the administrator, expiration date of the name registration and date of the creation of the domain name. Of course, everyone can keep their data private and this can be achieved by subscribing to a privacy service with which everyone will be able to know who owns the domain, but nothing more.

What are the obligations I must meet to use WHOIS?

Of course, when contracting a service, there are certain policies that allow us to maintain control within the service. These policies indicate to the person interested in registering a domain the way in which the service provider works, what it will give us, but also what the interested party must Giving to this supplier is a mutual agreement because a service contract is sealed. If both are clear on what each one must comply with, the success of the employment relationship will be guaranteed. It is because of some of the obligations that we must fulfill if we want to use WHOIS are the following.

Obligations to resellers and grantors of domains

Of course, as it is a very good service, it is possible that there are several providers, including resellers, this should, as far as possible , try to ensure that the registries comply with all WHOIS obligations , especially if these resellers participate in facilitating the registration of a domain name.

Data custody

ICANN, a corporation that has been in charge of assigning names and numbers on the Internet since 1998, the year it was launched, strongly requires registrars to provide an electronic copy of the respective registrar’s database, which of course must include WHOIS data. to a trusted data protection and custody service distributor, according to a schedule, according to the conditions and formats specified by the aforementioned corporation.


The presentation and privacy services are aimed especially at those people or companies that want to keep their information protected by preventing it from being in the public domain through the WHOIS system. In this sense, there are two privacy categories that will give the interested party the opportunity to choose between one and the other . The first is the privacy service through which alternative data or contact information is published in the WHOIS system. These data must be be reliable and can be a telephone number or address that will be kept in the registry as a user who benefits from the domain name.

The other category has to do with representation or proxy, in these cases the provider registers the domain name and grants its respective license to the client, publishing the contact information of the privacy service provider but not the client’s information by Therefore, the representation service acquires the responsibility of supplying exact contact information in order to give smooth course to any situation or problem that may occur in relation to the domain name.

These are some of the benefits of using the WHOIS protocol

All companies that register domains are obliged to make public by any means, especially through their website, the conditions related to the benefits and responsibilities of the people and companies that register their domain, including a link to access it. document, so that anyone can consult and be aware of both their duties and their rights, one of these benefits are the rights to a domain registrar, let’s see what it consists of.

Rights to the registrar of a domain

The rights of the different people who register a domain are linked to the instructions , which must be detailed and clearly explain the processes for registering, transferring, managing, renewing, and even reestablishing domain name registrations.
