If you find that QuarkIP’s Datacenter IPv6 proxy meets your needs, we recommend renewing as soon as possible to avoid service interruption due to expiration and IP release.
You can extend your proxy subscription by clicking the “Extend” button on the Proxy Management page and choosing to renew for 30, 90, 180, or 360 days.

The new expiration date will be the sum of your current remaining time plus the extension period. For example, if you have 15 days left and renew for 30 days, your total usage period will be 45 days.
If manual renewal feels inconvenient, we suggest enabling the Auto-Renewal feature and keeping sufficient balance in your account. The system will automatically renew your proxy three days before expiration and send you a notification email.
