The Internet Domain Name System called DNS is made up of a network of servers responsible for translating IP addresses, used by computers to identify each other on the Internet, to names that are more familiar and easier for people to remember.

These servers, called DNS servers, use specialized programs that implement communication protocols to maintain and update information regarding the IP addresses associated with domain names and to communicate this data to computers that require it from anywhere on the Internet.

DNS servers perform this task in a distributed and hierarchical way because the volume of information on the IP addresses and domain names of all computers on the Internet is very large and access to them is required every second by thousands of users.

The technical tasks of managing the DNS database for the domain names that are under the top-level domain PY (Paraguay) and of delegating the subdomains to those who request it are carried out by the NIC.

NIC is therefore responsible for the operation of the DNS for the PY domain. The organizations to which the NIC delegates domain names are in turn entirely responsible, administratively and technically, for them and their eventual subdomains.

As a consequence, the proper functioning of the DNS depends on the cooperation of all those who exercise the management of some segment of the domain name space, who thus become co-responsible for the organized and controlled growth of the network to guarantee the Internet Community its availability and accessibility at all times.

Due to what is indicated in the previous section, the Responsible Organization of each delegated domain must ensure that it works correctly. This implies that the operation of the name servers must be carried out with sufficient technical competence, aiming at a permanent availability of the service.

It is widely accepted by the Internet Community that domain names are delegated solely for use. This means that a certain domain name should not be requested for the sole purpose of reserving it for future use or to prevent others from using it.

Likewise, it is considered a negative practice the act of requesting the delegation of a certain domain for the purpose of selling it, anticipating that there will be other interested parties in using it. This practice is known as cyber-squatting and currently represents a constant concern for the various NICs.

The delegation of domain names is not related to the trademark registration system, so the sole purpose of protecting the trademark does not constitute sufficient support for the delegation request. It should not be forgotten that a domain is delegated to be used.

In this sense, it should be remembered that the trademark registration system allows the duplication of names because there are several dozen classes that separate them according to the different markets, a phenomenon that is not reproduced in the DNS organization, where normally there is a single scope available to all commercial companies and brands.

Therefore, the fact of having a registered trademark is independent and does not in itself grant you a special right before the NIC-PY to obtain a domain name of the same or similar denomination that has already been delegated. However, it should be noted that the use of a particular domain name is always subject to all applicable laws, including those concerning trademarks and other types of intellectual property.
