List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Mon, 17 May 2021 18:58:18 -0000 As discussed privately with Dave, I have removed the starlink provided router and replaced it with a Mikrotik RB2011 to allow for more granular control, and to better tie into my existing network. This has allowed me to make a dhcpv6-pd request that is reasonably stable (so far it has changed once in the last 2 months). The lease time is incredibly short, which is a little strange but as long as the DHCPv6 server is the same and remains unchanged, it should just hand out the same prefix upon request. I also built a very crude measurement display that just uses curl get and dig via smokeping to display reasonable RTT. It's detailed in the reddit post here: https://www.reddit.com/r/Starlink/comments/mykxjv/functional_ipv6_and_some_crude_starlink_latency/ and can be viewed directly here: https://starmon.qosbox.com/ Making dhcpv6-pd work is pretty standard: /ipv6 dhcp-client add add-default-route=yes interface=ether2 pool-name=starlink-ipv6 prefix-hint=::/56 request=prefix On each interface you want to have IPv6 on: /ipv6 address add address=::1 from-pool=starlink-ipv6 interface=bridge.8 add address=::1 from-pool=starlink-ipv6 interface=bridge.6
