IPv6 support on Virgin media

[dgcarter]

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

Was doing a wireshark capture of my router's WAN interface and in the router advertisement packets there is 2 /64 prefixes given in the RA packet. Will probably try tonight when no one in the house is using the network

If you are seeing prefixes similar to the one's described here: https://jamesmacwhite.medium.com/have-virgin-media-enabled-ipv6-sort-of-9443e5e855d

They have been present for a while, I asked someone at Liberty Global and they said it's nothing new.

One of them is a management network the other you technically can configure an IPv6 address within and get connectivity, but you won't be able to use prefix delegation as it's deliberately filtered out. You'd have to manually provision an IPv6 address within the correct subnet to use it.

Ahhh I see

Strangely enough, IPV6 usage in the UK appears to be dropping recently.

Comparing with APNIC, there's certainly a noticeable decline in 2021, although appears to have pretty much returned back to previously all time high IPv6 usage. I assume Akamai's is only measuring requests to their CDNs, where as APNIC is much wider.

Shout out to the 0.12% IPv6 usage under Virgin Media's ASN.

Oh, no. That was just me, switching from A&A to VM. 😉

As to these advertised prefixes, has anyone tried using proxy ND to put their entire network onto one? How did it go? Would it even work, i.e. is there any filtering of usable addresses in that space?

I've been tinkering with this myself. I've managed to set an IPv6 & can see ping requests from an external service via tcpdump but I cannot get any outgoing connectivity at all, I assume I must need to use a gateway but I'll be dammed if I can find an IPv6 one on VM!

[adhawkins]

If that graph is set to monitor an IPv6 address, then your 'router' must be sending ping replies to it. As such, it's probably your router not passing out correct details to the devices on your LAN if IPv6 isn't working.

The BQM is IPv4 only. I have no trouble setting a static IPv6 but I cannot for the life of me get any outbound IPv6 connections on the router but I can see IPv6 ping requests via tcpdump if I request a test from an external service. I assume I must need to set an IPv6 gateway & so far I cannot figure out what that is on VM. I'm used to setting up Virtual machines remotely with static IPv6 but for those you get given an IPv6 gateway, maybe I'm being a bit thick and missing something here.
