    Almost 9 years late to this post but here it goes in a nutshell.

    prefix-length and netmask arguments are just sanity checks.
    you could assign a nat pool like 100.100.100.0-100.100.100.255 but there could be issues if you got IPs .0 or .255 because they are network id and broadcast id. But if you use arguments prefix-length or netmask, those two ip addresses would never be mapped.

    So, arguments prefix-length and netmask prevent network id and broadcast address from being mapped.
