How to check the domain registration expiration date of a third-party site?

To check the domain registration expiration date of a third-party site, you can use the WHOIS lookup tool provided by ICANN (Internet Corporation for Assigned Names and Numbers).

Here’s how you can use the WHOIS tool to check the expiration date of a domain:

1. Go to the ICANN WHOIS lookup page: https://whois.icann.org/en
2. Enter the domain name of the site you want to check into the search field and click “Lookup.”
3. The WHOIS tool will display the registration information for the domain, including the expiration date.

Keep in mind that some domain registrars may choose to hide their registration information using WHOIS privacy protection services. In these cases, the WHOIS tool will not be able to display the registration information.
