- Proxy allocation usually takes 2–3 minutes while QuarkIP confirms the payment and assigns the proxy. The status will show “Allocating” until this process is complete
- QuarkIP static proxies support both HTTP and SOCKS5. You do not need to change the port when switching protocols
- Prepare the proxy protocol, host, port, username, and password
