on fast.com even i am getting over 100mbps in speed test with 50mbps plan. probably that is for within the country servers. outside it is same

are you using ipv4?

You mean it's slower than IPv4?

Google DNS, using with stubby for DoT. Default MTU set by OpenWRT which is 1460.

Mi Router 3G running OpenWRT. Over wireless, but should be similar over wired too.

Yeah, I meant IPV4.

I'm getting slightly higher pings and slower speed on IPV6. Don't know what I'm doing wrong.

Yeah, the high speeds seem restricted to fast.com. I'm yet to try IPv6 downloads.

I am getting exactly same speeds on IPv6 and IPv4. BTW, speedtest.net app on iOS and Android has gone dual stack.

ITsjefen, Trondheim (Norway) server is IPv6 enabled. Try it from app.

Speedtest by Ookla - The Global Broadband Speed Test

Use Speedtest on all your devices with our free desktop and mobile apps.

www.speedtest.net

It shows your IPv6 in the app when you view past results.

Facing deep lag on ipV6 browsing and lots of websites not opening. I also tested with google ipv6 DNS. Switched back to ipV4.

So I setup a VM in DigitalOcean Bangalore and tried iperf3 over IPv6

Code:

[ ID] Interval           Transfer     Bitrate

[SUM]   0.00-20.00  sec   602 MBytes   252 Mbits/sec                  receiver

iperf Done.

Exact same test over IPv4 gives this

Code:

[ ID] Interval           Transfer     Bitrate

iperf Done.

Also, the high speeds might be only for traffic which is directly peered, just a guess. Over IPv6, most networks seem directly connected but the latency seem higher, unsure if they are doing some tunnelling or something of that sort.

It is a bit strange that a traceroute shows most of the destinations as directly connected, however looking at https://bgp.he.net/AS9829#_peers6, these networks are not directly peered.

Not sure why the trace routes for me show the intermediate networks missing.

@sanke3 You are on MTNL right? That doesn't look like BSNL's IPv6 range.

IPv6 being issued by BSNL Broadband!
