IPv6 support on Virgin media

Does anyone know whether (and if so when) Virgin plan to implement IPv6 on its network?

Here's my situation as of this morning:

IPV4 196 Mb/s

IPV6 72.5 Mb/s

I've only just set the tunnel up so I can't compare it with previous days.

72.5 is pretty good by current standards,

What tunnel provider and endpoint?

What kind of VM modem/router do you have?

Are you running it in modem mode?

    Interesting we are seeing pockets of increase speeds in some cases, for myself I figured out getting iperf3 to work properly with multi WANs so it's actually testing the right WAN.

    I see no change in my case currently.

    Maybe we need to start trying to see if routing is anything to do with it, this is my HE tunnel endpoint and the path.

    I'm in Edinburgh, with a superhub 2 running in modem mode. The router is a Netgear 3700 running Openwrt and the HE tunnel is set up on that, connecting to the London endpoint on 216.66.88.98

      Okay...

      I'm in Bracknell and I have a 500 Mbit/s VM Business connection with a Hitron router running in modem mode. My router is an Apple AirPort Extreme (the final model 802.11ac tower with the latest [final] firmware). Over IPv4, depending on how I measure, I can get up to 550 MBit/s downstream and 35 Mbit/s upstream.

      My primary tunnel is Hurricane Electric (tunnelbroker.net) to the original London endpoint (216.66.80.26). Originally my tunnel terminated at the AirPort Extreme router but as part if my recent investigations (and avoidance measures) for this issue I have changed my setup...

      I now have *two* separate tunnels active from my home location:

      1. My original HE tunnel to the same endpoint but now terminated on my Synology NAS which is acting as a router and firewall for IPv6 traffic *only* (all IPv4 traffic [including the tunnelled protocol 41 traffic of course] still goes via the AirPort Extreme and the Hitron over my VM connection.

      Over this tunnel my typical performance (it varies marginally over time) is:

      HTTP: 28 Mbit/s
      IPERF3 (single stream): 22 Mbit/s

      I run automated http speed tests on this connection every 20 minutes and log the results for later analysis.

      An IPv4 traceroute from this system to the tunnel endpoint looks like this:

      traceroute to 216.66.80.26 (216.66.80.26), 30 hops max, 60 byte packets

      2. A second tunnel to the London endpoint (45.12.68.66) of tunnel broker.ch. This terminates, at my end, at my second Synology NAS and provides IPv6 services only for that unit (not my entire network). The underlying IPv4 traffic for this also, of course, goes via my AirPort Extreme and the Hitron over my VM connection.

      Over this tunnel my typical performance (it varies marginally over time) is:

      HTTP: 31 Mbit/s
      IPERF3 (single stream): 23 Mbit/s

      An IPv4 traceroute from this system to the tunnel endpoint looks like this:

        I also have a third tunnel to Hurricane Electric's second London endpoint (216.66.88.98). This tunnel runs between a Linux cloud hosted VM (in the Oracle Cloud London data centre) to the HE endpoint and does not traverse any VM infrastructure. This VM has a 2 Gbit/s bandwidth for Internet connectivity.

        Using the same IPv4 measurement techniques as I do from home I typically see around 816 - 970 MBit/s for http and iperf3.

        For IPv6 over the tunnel I see between 594 and 619 Mbit/s. Slower than IPv4 for sure but [perfectly acceptable given I am using a tunnel.

        The IPv4 traceroute to the tunnel endpoint looks like this:

        I don't see any obvious issues in the routing but frankly without knowing a lot more detail than we have it is hard to draw any real conclusions other than 'VM network is terrible for 6in4 traffic'.
