After you provision the IoD service, you have everything you need to bring up IPv4 and IPv6 BGP sessions however the portal is missing the IPv6 interface subnet mask.
I reached out to the NOC and found that the typical subnet mask is /126.
Hopefully the automated information will get updated to provide this information as well as shortened IPv6 addresses. I had to use an IPv6 address compressor to make sure I had computed it correctly manually.
