# Expiry ### **What is Expiry in PNS?** Expiry in PNS is like a timer for your .pls domain names. It tells you how long your domain name will work and how long the settings (fuses) you choose will last. ### **How Does Expiry Work?** * When you set an expiry for a domain, it's like setting an alarm. Until the alarm rings (expiry date), your domain and its settings (fuses) keep working. * For .pls domains, the expiry date is automatically matched to a date set in the PNS system. But for other types of domains, the person who owns the main domain (parent) can decide how long each subdomain (child domain) will last. ### **Maximum Expiry for Subdomains** * The longest a subdomain can last is as long as its parent domain. * For example, if your main domain is good for 5 years, then the subdomains can also be set for up to 5 years. But the parent can choose a shorter time, like 2 years, if they want. ### **Different Expiry for Different Subdomains** * The parent can set different expiry times for different subdomains. Just like they can set different fuses for them. ### **Renewing Domain Names** * When you renew a .pls domain, its new expiry date is updated in both PNS and the original system. * However, renewing a main domain doesn't automatically renew all its subdomains. * The parent can renew a subdomain's expiry at any time, even if it's already independent (emancipated). * Parents can also allow subdomain owners or others to extend the subdomain's expiry. ### **Special Settings for Subdomains** * Parents can use a special setting (CAN\_EXTEND\_EXPIRY fuse) that lets subdomain owners extend their own expiry. * This is handy if you're managing lots of subdomains and want to let them handle their own renewals. ### **Special Cases for .pls Domains** * For .pls domains, the expiry date includes a grace period after the actual expiry date. * During this grace period, you can't make changes to the domain, but you don't lose it right away. You just need to renew it to regain full control. ### **What Happens When a Domain Expires?** * If a domain just has its settings (fuses) on but isn't locked or emancipated, the fuses reset when it expires, but you still keep the domain. * If a domain is locked or emancipated and it expires, you lose ownership of the domain.
