You must renew your domain name to keep it active. The domain registrar that provided your domain should send you a reminder before it expires. Many registrars also have an auto-renew option that helps ensure your domain name never lapses.  If you don’t want to pay for your domain every year, your provider may give you the option to extend your domain for multiple years by paying upfront. This is a good way to lock in your rate, and you don’t have to worry about renewing your domain annually.
