Self-hosting on Starlink: CGNAT, IPv6 & blocked ports
What public sources say about running a home server, VPN or remote access on Starlink. We only list values we could source. Anything blank is unknown, not a "no".
Residential
| What | What the source says | Source |
|---|---|---|
| Behind CGNAT by default? | Yes - default IPv4 is CGNAT (100.64.0.0/10) With CGNAT, many customers share one public IPv4 address, so port forwarding on your router cannot make a home server reachable from the internet over IPv4. | ISP official page Checked 2026-10-15 |
| Native IPv6 | Yes on all routers/plans; /56 delegated via DHCPv6-PD With native IPv6, each device can get a globally routable address, which is one way to reach a home server even when IPv4 is behind CGNAT (if the remote side also has IPv6). | ISP official page Checked 2026-10-15 |
| IPv6 prefix size | /56 | ISP official page Checked 2026-10-15 |
| Public IPv4 (may change) | Optional public IPv4 only on Local/Global Priority plans, assigned by DHCP | ISP official page Checked 2026-10-15 |
| Static IPv4 on residential plans | No - 'truly static IPs are not available' (public IPv4 kept via reservation) A static IP never changes. A public dynamic IP plus dynamic DNS is enough for most home servers; a static IP matters for mail servers and allow-lists. | ISP official page Checked 2026-10-15 |
| Bridge / passthrough mode | Starlink routers do not support port forwarding; use a third-party router with Starlink router in bypass mode Bridge or passthrough mode lets your own router take the public IP so you control the firewall and port forwards. | ISP official page Checked 2026-10-15 |
