Not yet, I plan to introduce ranges in 0.7.0, I'm still working on a
meaningful notation.

No, it will assume the classful subnet mask (/8 in this case)

However this behaviour is currently under discussion, as it is one
major break in respect to IPAddr (the other being #to_s). It may
change in the future.
