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.

📘 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.

As a mobile user moved between regions and migrates between ground stations they will acquire a new IP as they move between ground stations.

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 Priority, 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

Starlink will allocate:

• One public IPv4 address for the customer’s wide area network (WAN), provisioned via Dynamic Host Configuration Protocol version 6 Prefix Delegation (DHCP) for routers/firewalls using IPv4.
• One IPv6 /64 prefix for the customer’s wide area network (WAN), provisioned via Stateless Address Auto Configuration (SLAAC) for routers/firewalls using IPv6.
• One IPv6 /56 prefix for the customer’s local area network (LAN), provisioned to routers capable of issuing a DHCPv6-PD request.

IPv6 is supported on all Starlink routers.

👍 IPv6 Native

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