WHOIS

WHOIS is a public database that contains information about domain names, IP addresses, and other internet resources:

What it contains

WHOIS records include the name and contact information of the domain owner, the registrar, the registration and expiration dates, and more

What it's used for

WHOIS is used to verify domain names, resolve technical issues, and investigate cybercrime

How it works

WHOIS is a query and response protocol that stores and delivers information in a human-readable format

Who regulates it

The International Corporation for Assigned Names and Numbers (ICANN) regulates the WHOIS database

Who maintains it

Different domain registrars and registries manage the WHOIS database for specific TLDs, such as .com and .net

WHOIS is a vital tool for maintaining the integrity of the domain name registration process. However, there are some limitations to WHOIS lookup:

• Some TLDs, like country-code level domains (.us, .ca, .uk, and .eu), don't support privacy options.
• Regulatory adjustments, like the GDPR in Europe, may remove some previously stored information.
