## Static IP overview

A static IP address, as opposed to a dynamic IP address, is a permanent, non-changing network address that identifies a device on the internet. It is a 32 bit number in the form of a dotted quad (IPv4 format), for example, 192.168.0.12. A static IP address is typically provided by an internet service provider and informs servers of the location of a specific device.

## Public IP overview

A public IP address is an external-facing IP address used to access the Internet. Public IP addresses are provided by the internet service provider (ISP) and assigned to the router. It is a unique IP address on the internet.

## Which IP to supply

To make sure that you provide us with the correct IP address we recommend that you speak with your company's internal IT department. They should provide you with the correct IP address for us to allowlist/whitelist.
