The network address would be 128.139.0.0. The individual host
addresses would be 128.139.0.1 to 128.139.255.254.

Yes.

IP addresses and netmasks are just 32-bit numbers. For a given IP
address and netmask, the network address is obtained by AND-ing the
address with the netmask, while the broadcast address is given by
OR-ing the address with the one's-complement of the netmask.
