# Static IP for Angel One SmartAPI

Register a dedicated Fixedmark IPv4 pair as the primary and secondary static IP of a SmartAPI app, changeable at most once a calendar week.

Docs preview: Fixedmark is not live yet. Endpoints are issued at launch, and these pages describe planned launch behavior. Anything marked planned may change. [Join early access](https://fixedmark.com/early-access) to get yours first.

## 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](https://support.zerodha.com/category/trading-and-markets/general-kite/kite-api/articles/static-ip) 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](https://fixedmark.com/docs/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.

- Per [Angel One](https://www.angelone.in/news/market-updates/what-s-changing-in-angel-one-s-smartapi-access-from-april-1-2026), order requests are processed only when they come from your registered IPs.
