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.
