• Do you support and publish the full IPv6 BGP Routing Table?
  • If not what portion of the BGP Routing Table do you support?
  • Are full IPv6 global routes available to end customers?
• Do you host and provide the access to a “looking glass” IPv6 BGP router, for the troubleshooting purposes?
• Do you accept and announce /48 blocks?
• What is the smallest prefix you accept?
• What is the smallest prefix your upstream providers accept from you? Are there any restrictions on prefix advertisements?
• What percentage of your IPv4 peers to you currently peer with for IPv6?
• Are you partitioned from any other major networks? (i.e. lacking global reachability to other major networks) (Reference)?
  • Will the provider disclose its list of IPv6 peerings, indicating which IPv6 peerings are native and which are tunneled?
• Does the provider have a policy in place regarding deployment of tunnels on its backbone network or with peerings?
  • In other words, is there any IPv6 tunneling on the provider’s backbone network, and if peerings with other providers currently exist which are tunneled, does/will the provider have a policy in place which will mandate peerings with providers be native?
  • What MTU restrictions or standards are in place for any tunnels?
