About
Sixup is a single static Linux binary that replaces odhcp6c, radvd, odhcpd, and ndppd with one fully automatic IPv6 router daemon. It handles DHCPv6 prefix delegation, router advertisements, a DHCPv6 server, NDP proxying, and DS-Lite/MAP-E tunnels, consolidating tools network operators previously had to run and configure separately.
At a glance
Sixup combines IPv6 prefix acquisition, LAN advertisements, DHCPv6 and related router functions in one Linux daemon. It is worth evaluating if you currently glue several services together to keep a small network working when the upstream prefix changes.
Good fit
Linux router operators with an isolated lab and a known WAN and LAN topology.
Consider something else when
Keep your existing setup when the router cannot be taken offline or must satisfy requirements still marked incomplete in the project’s standards matrix.
Start here
Read the standards matrix and use the documented dry run on an isolated WAN. Check the offered prefix before testing client addressing and inbound firewall behavior.
Cost and requirements
MIT-licensed Linux software. Operating it as a router requires privileged network access and the correct interfaces.
Limits to know
The daemon manages addressing and firewall behavior. Verify your ISP’s prefix or tunnel arrangement and keep a rollback path before replacing live services.

Why it made the leaderboard
Consolidating fragile multi-daemon IPv6 router configs into one binary meaningfully simplifies self-hosted and home-lab networking setups.
