Thanks for the tests!<br>

The dl/ul speeds 300/15 mbit/s are impressive.<br>

<p>"Speeds" (observed data rates) in terms of Starlink hardware are
actually fairly meaningless as they depend on:</p>
<ul>
<li>Satellite(s) involved in the data transfer over the duration
of the measurement(s).</li>
<li>Load on those satellites, which depends on the number of other
current users whose traffic goes via those birds, and what these
users are up to. Note this changes between handovers.<br>
</li>
<li>RTT to other end of transfer path.</li>
<li>Packet loss (including beyond Starlink's network)</li>
</ul>
<p>Unless a Dishy is able to handle communication via multiple
satellites in parallel, I would expect the rates to be the same
more or less regardless of model used. In fact, I would expect a
Dishy model that is able to align itself to do marginally better
over time.<br>

At video pointer 5:53 the reported Ping ?/dl/ul 88/204/121 ms and
Jitter <br>
9.2 ms seem interesting.<br>

name 'latency'?<br>

All of them I guess.<br>

Because that is where you have the longer queues.<br>

<p>I presume unloaded ping RTT. The second is ping RTT during the
download test (with inbound queues loaded), the last is ping RTT
during the upload test (with outbound queues loaded).</p>
<p>I'd also note here that these are values obtained from Kyiv,
which isn't a Starlink environment that is easy to assess. For
one, we don't know whether there are Starlink gateways in Ukraine,
or if there are, where they'd be. We know that there aren't any in
Russia or Belarus. We know that there are gateways in Turkey,
Poland and Lithuania and further afield that can reach satellites
that users in Ukraine can reach by direct RF link. We don't know
where else there may be gateways - not every jurisdiction
publishes this - or whether Starlink may even be operating
opportunistic fair weather optical gateways which they don't have
to disclose to anyone. Plus we don't know what may be carted into
the area or away from it via laser links to gateways much further
away. <br>

I wonder whether the DHCPv6-PD is still supported by REV4 and
whether <br>
the allocated prefix is still a non-/64 (i.e. a /56 delivered by <br>
DHCPv6-PD reported earlier on this email list by Steven on Dec.
12, 2023)?<br>
