Alexandre,
Are you sure the DHCPv6-PD server is in Starlink network and not on the
MikroTik router?
That would be quite the unusual setup, and even so would require that
I obtain said /56 from elsewhere (such as via a tunnel) to then
delegate back to myself...
True, it would be unusual, but it is practiced.
It could be that the MikroTik router runs tunnelbroker, obtains a /56
from HE, splits that /56 into multiple /64s and puts it on the
DHCPv6-PD
local server config files.
I am confident this is not the case since I configured these routers
from scratch.
It could also be that the DHCPv6-PD server is run on the Dishy.
It is unlikely that it is on the Dishy, as the latency to the DHCPv6
servers IP address, as well as the first IP hop, indicates the usual
Ground->Space->Ground latency I'd expect.
YEs, that latency argument is a good reason.
It could also be that the DHCPv6-PD server is run on the starlink
ground
network: maybe on the teleport, maybe deeper on the starlink network.
Yes, this is the most likely place they are running this, likely the
PoP you are being routed through.
Do you know the IPv6 address of your DHCPv6-PD Server?
The DHCPv6 server address is a Starlink IPv6 address, the same one as
my default gateway (`2406:2d40:xxx:xxx::1`). The /56 I am being
allocated is also from the same /32 as this DHCPv6 server, with the
/32 being 2406:2d40::/32, which you'll note is allocated to Starlink.
Thanks. That convinces me it is as you say: the /56 is provided by
the starlink DHCPv6-PD server situated in the ground network of
starlink somewhere.
This makes it for a great tool for many things.
Sorry for having been cryptic about 'many things' - I meant to say that
I hope that MikroTik querying the DHCPv6-PD server in the starlink
infrastructure might work ok from a car as well. This would be one big
advantage of using starlink instead of a 4G-5G link in a car (the 4G-5G
cellular networks only give /64s to end users, and the android
smartphones dont run DHCPv6-PD Clients).
