Have Virgin Media enabled IPv6? Sort of…

Luke’s tweet around IPv6 connectivity.
Luke showing test-ipv6.com results as 10/10 with a manually configured IPv6 address from a valid Virgin Media IPv6 subnet.
  • 2a02:8800:f000:18b0::/64
  • 2a02:88fd:18:a::/64
  • No IPv6 direct peering with Cloudflare (the traffic goes via Telia instead)
  • Comcast IPv6 is completely inaccessible at the moment (although this might be just transient, apparently Liberty Global were having some “difficulties” configuring their networking equipment earlier…)
