Internet Corporation for Assigned Names and Numbers (ICANN) is a non-profit organization responsible for Internet Protocol (IP) address space allocation, generic and country-code Top-Level domain name (gTLD) system management.
What is ICANN Verification, and how to do it?
ICANN is the organization qualified for setting the various policies and procedures that direct domain registries for generic top-level domain (gTLD) names.
Each registered domain is required to present identifying contact information for the Registrant (owner), administrator and billing contacts, including full name, postal address, email address and phone number. This data referred to as "WHOIS data," and it is included in the domain's record in the public WHOIS database.
The main job of ICANN is to coordinate the names and numbers related to internet addresses and not register domain names.
When a new domain is registered, an email to the Registrant's email address specified for the domain to verify contact information is become valid by agreeing on a link involved in the confirmation email. The verification email will also be sent if edit action made to either of the following Registrant contact fields:
1) Registrant First Name
2) Registrant the Last name
3) Registrant Email Address
Internet Corporation for Assigned Names and Numbers manages a variety of naming systems. You can run into a dispute over a domain name that violates your brand or intellectual property; ICANN is where you'll want to go to solve the conflict.
1) ICANN divvies up IP addresses and gives them to the five main registries worldwide.
2) ICANN handles the registration of DNS registrars but does not manage the costs of domain names.
3) These are the servers at the base or "root" of your DNS authority, and ICANN correlates with them to assign IP addresses.
