I'm sure they use carrier grade NAT, yes. However, nothing would prevent them from using a unique public IP assigned to them for their DNS servers like others do. Using RFC1918 space for a routed destination of an ISP service (DNS) is particularly problematic for many VPN client configurations with corporate address range overlap. -Paul On Thu, Jun 28, 2012 at 1:40 PM, Christopher Morrow <morrowc.lists@gmail.com

Why they don't use public IP space belonging to them for DNS servers, I do not know.
