Unlikely, although it might be an interesting case of testing ARIN's =

Probably. I've heard other large providers having similar issues =

Yes, however at the time those ISPs squatted on those addresses (and =

This would assume their deployed systems can support IPv6. I suspect =

short-term upgrade costs (or deal with additional operational costs if =
they used multiple instances of 10/8). But I'm just guessing...
