# Do I need a static IP address, and how do I get one on nbn?

When a fixed IP address is worth having, and how to add one to your plan.

Most nbn plans use a dynamic IP address, which can change from time to time. A static IP stays the same permanently, which some setups depend on.

## When you need one

Running your own mail server, hosting a website from your premises, needing reliable remote access to security cameras or business systems, or running a VPN endpoint that other locations connect to by a fixed address.

## When you don't

General browsing, streaming and most cloud-based business software (including most VPN client setups) work fine with a standard dynamic IP.

1. **Confirm you need one** - Talk to us or your IT provider about whether your specific use case requires a static IP.
2. **Add it to your plan** - We can add a static IP add-on to eligible business nbn plans.
3. **Reconfigure your equipment** - Your IT provider updates the relevant device or service to use the new fixed address.
