Make sure your wallet has sufficient funds:
1. Open your Dashboard, click Static ISP Proxies
2. Click IP Management
3. Choose the IP you want to renew, Click Renew
Note that you should renew your IP before it expires.
Tip: If you want to ensure that you purchase before expiration, you can try the automatic subscription function in the PY wallet; select the package you want to renew, filter the ip that needs to be renewed, and click auto-renew.
