3BB and (some) benefits of IPV6

[muratremix]

I decided to visit http://ipv6-test.com/pingtest/ for no reason today. I've noticed ipv6 ping towards Germany (OVH) was significantly lower than IPv4. So I found a test IP from OVH looking glass and tested if that was the case:

 

 

Here is IPv4 version (UDP)

 

Some basic speedtest from ipv6-test.com 

 

 

Conclusion:
use IPv6 if you can.

You cannot make conclusions like that ????

Average ping time from here (Bangkok AIS) for ipv4 is 7.608 ms and with ipv6 7.531. This is about the same. 

 

Routing for ipv4 and ipv6 can be different, so it is possible that ping times are different. But this is not a result of something being ipv4 or ipv6. It's the result of using different ways to reach the destination. In another case ipv4 can be faster.

 

One thing surprises me...  My ping time is about 7 ms, yours is about 200 ms. Is 3bb really so bad ?  It looks like they are trying to save money on international connections.

You're pinging from your VPS in Europe and you think 200 ms from Thailand to Europe is too much? There is no FTL or Wormhole travel for photons yet so latency is expected.

 

I'm getting 161 ms to OVH France via IPv6 and 210 ms with IPv4 and I'd say that's a major difference.

You won't get any noticeable difference when ping is as low as 7 ms, I'm not saying IPv6 is faster, it is faster but not that much. 

 

It means that next time I install openvpn to any VPS or Server of mine, if I use IPv6 to connect I'll get 20-50 ms lower ping which is great. Since IPv6 traffic is pretty low (compared to IPv4) it is also faster too.

 

I had similar experience with AIS before, I got faster speedtest with IPv6 vs IPv4 (CGNAT)

I've had IPv4 and IPv6 every since being with AIS Fibre and I've found IPv6 to "usually" be faster...usually by just a little bit to most locations but some times a lot faster.   But to other locations at other times IPv4 will beat out IPv6.  When a person "averaged out" all the test run to different locations on different days at different times, IPv6 was the winner over IPv4.

 

Before I did tons of speed tests using various speed testers that have both IPv4 and IPv6 speed testing capability like nperf.com and came to the conclusion IPv6 was usually a little faster than IPv4 connections.  And with less people using/having IPv6 capability maybe I could bypass of the traffic jams on IPv4 connection highways.   

 

With the Nperf.com speed tester you can check various servers/locations around the world....find those places which have both IPv4 and IPv6 servers and then run some tests.  Like below test I did to Singapore....first snapshot is the results with an IPv4 connection/server; 2nd with an IPv6 connection/server.  I'm just using a old laptop with Wifi connection for this test...the test is only meant to show the relative speed difference between an IPv4 and IPv6 Nperf speed test to the same location....not meant to show the max speed possible where I should do the test with an ethernet connection.

 

I would also use the ipv6-test.com when they had more testing locations but only have few now.   But I did do one speed test using ipv6-test....see the last snapshot...IPv6 won that speed race.
