Answers to frequently asked questions about Whois

What means WHOIS?

WHOIS is a network protocol that is based on the TCP protocol. By default, it uses port 43 for operation. It is widely used to display information about records on the Internet (domains, ip-addresses, nickname handles), helps to determine who owns the domain and how to contact him. The Internet Corporation for Assigned Names and Numbers (ICANN) regulates the registration and ownership of domain names.

What is the purpose of WHOIS?

WHOIS is designed to obtain information in text form about the owners of Internet objects - domains, IP addresses, nickname handles, etc.

Is WHOIS illegal?

According to ICANN rules, WHOIS data about the owner of the domain must be open and up-to-date. Fictitious data in WHOIS is one of the most common causes of domain denial of service by a registrar. WHOIS may only be used for lawful purposes. The use of data obtained from WHOIS for the purpose of sending spam, marketing offers and the like is prohibited. It is also prohibited to perform multiple requests to WHOIS for the purpose of mass collection of information.

Can you lie on WHOIS information?

For a number of reasons, many registrars do not enter real data about the domain owner in WHOIS, or replace contact information with their own (proxy contact). This is due to the privacy policy and protection of personal data of customers.

Who owns IP address?

The management and assignment of IP addresses on the Internet is handled by the American organization - IANA. The organization is responsible for providing information about the IP address, managing the root zone in DNS, assigning ASN numbers, and other Internet numbers and symbols related to the Internet Protocol.

Do I have to use my real name when registering a domain?

When registering a domain, the reliability of contact information is not checked. However, in the process of using the domain, the lack of up-to-date information about yourself may be the reason for the loss or blocking of the domain.

What happens if I don't register my domain?

Along with the expiration of the domain registration period, the registrant's rights to the domain also expire. The registrar may provide a graceful renewal option after expiration, but this option is not available for many domains. At Ukrnames, most domains have a grace period of 28 days.

Does WHOIS always display information about the owner of a domain?

Once a domain is registered, in most cases the owner information is displayed in the WHOIS. There are times when data about the owner of a domain can be hidden, most often this is due to personal data protection policies.

Are there WHOIS access restrictions?

The WHOIS protocol works without restrictions - anyone can access the data without prior authorization. Technical limits on the number of requests, IPs from which requests are allowed, the completeness of the displayed data can be set by the holder of WHOIS - Administrator or Domain Registrar.

In addition to the owner data, what other information does WHOIS contain?

For domain names - WHOIS contains information about the date of registration, last modification and expiration of the domain, as well as information about the domain registrar. The ICANN org encourages registrars and registries of different countries to adhere to a single format and set of data displayed in WHOIS, however, this only works for gTLDs and newGTLD domains. For ccTLDs - WHOIS format is determined by the Administrator domain zone.

For IP addresses - WHOIS contains information about the number of addresses in the block, the owner, the IP block settings (route object).

How to get the WHOIS list of all domain zones?

An up-to-date list of WHOIS is available on the Internet Assigned Numbers Authority (IANA) website. You can find the list on the IANA website by searching for: Root Zone Database.

What are EPP Status Codes?

The domain status is inactive, what does it mean?
