Static IP for Kotak Neo Trade API

Before you start

• Use a dedicated pair. Pro and above give you two IPv4 addresses no other customer uses. The 7-day trial and Starter share their pair with other customers, and a broker such as Zerodha takes a static IP only for your own use or your immediate family's, so do not register a shared pair with a broker.
• Order the pair in Mumbai, nearest the exchanges, and copy both addresses from the dashboard.
• Send your orders through the proxy URL, so they leave from the addresses you register. Check with verify egress IP.
• Each broker decides what it accepts. Confirm with your broker that a dedicated cloud IP meets its rules before you depend on it.
