<p>Hi Mark,<br>
<br>
<outright sarcasm><br>
Yes. The raw Mbits/second value ends up being marginally lower in
almost all cases. And that's all that matters.<br>
</outright sarcasm><br>
<br>
I agree latency is the more important measure. Most (non-tech)
people don't reason like that.<br>
<br>
Kind regards,<br>

<p>So IPv6 is slower???</p>
<p>From my home in Pretoria, where I have a 100Mbps FTTH
connection via Telkom/Axxess - I can easily test ping times to a
server I have at Teraco in Johannesburg. Running ping
side-by-side, I see:-</p>
<p> Min Avg Max Mdev<br>
IPv6: 4.565/5.028/6.021/0.318 ms<br>
IPv4: 5.013/5.902/6.452/0.395 ms</p>
<p>Speedtest systems give me 105Mbps down and 95Mbps upload
speeds.... (to Durban???) - but do I really care? I'm more
interested in "how quick does that Website load" or "how fast
are responses to typing" - not "do I save a second in
downloading a 1.2GB movie"</p>
<p>Anyway - my Interactive interaction to my servers at Teraco is
faster on IPv6 than on IPv4 - not that I really notice a 1ms
difference!</p>
<p>Oh - I strongly suggest if you are in the Internet industry
then you should generally use your ccTLD based email address -
not Gmail/Yahoo - etc.</p>

<p>Hi All,</p>
<p>I'm looping back to this original email, not because I want
to answer here directly, but rather because I think it's
appropriate to consider the "bigger picture" of responses.</p>
<p>First and foremost, I've seen quite strong opinions from
newly registered @gmail.com addresses. I'd like to understand
the affiliation of these participants.</p>
<p>In my opinion there are a number of conflicting and not quite
obvious agendas in this, for this, and against this, policy
proposal - all of them with various commercial impacts for
various entities. Almost none of them to the benefit of the
"end consumer".<br>
</p>
<p>I personally believe the best thing is to retain the current
status quo *as it stands*, as this leaves operational
decisions to the various network operators rather than
enforcing operational issues by way of policy.</p>
<p>That said, I *personally* do not believe IPv4 should have a
future of any kind. Here I'm in agreement with Jordi that
networks should be deploying as IPv6-first.<br>
<br>
The *reality* however is that the world is predominantly IPv4
- "everyone" is connected using IPv4, and I don't (at least
not in Africa) see that this is going to change any time
soon. We've been debating the reasons for this in the office
the last week or two, and I'm not going to bore you with the
details, but our opinion is that this is not because networks
and techies don't want to switch but because customers (yes,
you read that right) demands that we don't. When you deploy
DNS for a customer - just dare try and ask for AAAA details
when only provided with A details and see the response you
get. Usually from people that should *know better*.</p>
<p>When people run speedtest (which I understand measures only
L7 throughput) and they get a lower value on IPv6 than on IPv4
... what's the next thing that happens? User logs into
router, find the "disable IPv6" button (or equivalent)
*click*.<br>
<br>
Okay, so follow the (apparent) European standard of users may
not have access to their routers where they're forced to have
IPv6 on and can do nothing about it ... had a discussion the
other day with someone in Europe about this, "I get better
throughput by putting my own router behind that of my ISP and
running IPv4 only on my own network" - where there's v6 only
... well, I've yet to hear/see about that end-network. Some
core networks sure I've heard of that.</p>
<p>As much as I hate to say this: IPv4 is going to be with us
for a while. And we should encourage deployment of IPv6, but
I don't think we can enforce that by way of policy as this is
interfering with network operational decisions/designs. I
also strongly disagree with apparent stances I've observed
hinting that we should make the soft landing more lax as that
just drives up costs for everyone much sooner and faster, and
in a world where everyone I communicate with are already
complaining about the cost of stuff I don't think that's fair
either.<br>
<br>
Kind regards,<br>
