IP Addresses

Starlink provides two IPv4 policies, "default" and "public", and always provides a public IPv6 /56 prefix.

🚧

Static IP

Starlink does not provide static IP addresses at this time.

The Starlink network is dynamic and from time-to-time IP addresses will change for resilience, as network capacity increases, or when new countries are added to the network.

If your network is using an IPsec VPN please configure a "dynamic peer" for the device connected to Starlink.

Mobile Users

If you have a mobile Starlink the IP address may change if you move locations. These changes will cause a brief DHCP handoff outage.

This is a fundamental limitation with how the internet works and is not a Starlink specific restriction. The internet is connected with stationary routers in data centers around the world to route traffic to the internet.

Starlink is a global service and has many different routers in different locations to provide the lowest latency connection possible.

Default IP (CGNAT)

The default IPv4 configuration is Carrier Grade Network Address Translation (CGNAT) using private address space assigned to Starlink clients using DHCP from the 100.64.0.0/10 prefix. Network Address Translation (NAT) translates between Starlink private and public IPs.

The default IP policy using CGNAT blocks all inbound ports. Customers requiring inbound ports should consider products with a public IP option. The following outbound ports are blocked for all customers per information security best practices: TCP/25 (SMTP) and TCP/445 (SMB).

Public IP

The Starlink public IP policy is an optional configuration available to Priority, Mobile, and Maritime customers.

A public IP is reachable from any device on the internet and is assigned to Starlink network clients using DHCP. Moving the Starlink to another location may cause the public IP to change. The public IP option can be enabled from the account dashboard.

IP Allocation

Each Starlink is allocated one IPv4 address and delegated a /56 IPv6 prefix for network clients. All Starlink network clients are assigned an IPv6 address if the router is IPv6 is capable. IPv6 is supported on all Starlink routers.

πŸ‘

Starlink is IPv6 native network. Using IPv6 is more flexible and future-proof.

Geolocation

All Starlink IP Subnets and geolocation mapping and can be found in the Starlink Geo IP Database

The list of Starlink points of presence (PoPs) are maintained in PeeringDB
