What do you want to know?
There's no "standard" for how technical information would be encoded into a domain name like that... there might be some rules that Bell Aliant is using when they construct those names, but you're going to have to guess at that unless you know someone who works as a network engineer for them.
You can find out some neat information about who owns your connection from the IP address... it should seem that the
142.166.0.0/16 IP address block is owned by the Stentor National Integrated Communications Network, which (I'm guessing, as they don't seem to have a website) is a nationwide network run by Aliant (Aliant's websites also fall into that address range).
