Admin Method - erification of the domain administrator’s e-mail address

Description of the method

Verification of domain access by clicking on a verification link that will be sent by Certum to one of the five permissible e-mail addresses of the administrator of the requested domain, such as:

  • admin@twojadomena.pl,
  • administrator@twojadomena.pl,
  • webmaster@twojadomena.pl,
  • postmaster@twojadomena.pl,
  • hostmaster@twojadomena.pl

For which domains is it available?

  • root domains,
  • first and subsequent level (including www) subdomains,
  • wildcard domains

How to carry out the verification?

  1. You can verify the root domain using:
    • root domain verification.
  2. You can verify a subdomain of any level using:
    • root domain verification, requested subdomain verification,
  3. You can verify a www subdomain using:
    • if you include in your application a domain or subdomain occurring immediately after the www subdomain:
      • root domain verification, verification of the domain or subdomain occurring immediately after the www subdomain,
      • requested subdomain verification,
    • if you did not include in your application the domain or subdomain occurring immediately after the www subdomain:
      • root domain verification,
      • requested subdomain verification,
  4. You can verify a wildcard domain using:
    • root domain verification,
    • verification of the domain or subdomain occurring immediately after the wildcard character,

Examples

  1. When requesting for twojadomena.pl, you can verify it with:
    • verification of the root domain twojadomena.pl
