Interesting. I requested exactly that when filling in their BGP
questionnaire, and they set it up - no questions asked.
Also, we have a perfectly normal single BGP session. The loopback
address of the router we're connected to is found within the 188.8.131.52/8
prefix, which they announce to us over that session like any other route.

I have been promised, in writing, that they will provide us with native
IPv6 transit before the end of the year.
I'm based in Europe, though. Perhaps they're more flexible and
customer-friendly here than in the US?
