I was provided a list of IPs and ranges, most of them were in the format of 1.1.1.1-1.1.1.4. Nmap doesnt like this format, nmap likes the format of 1.1.1.1-4. This is easy if everything is a /24. Most of my ranges were not. I used the iptools python module written for Django to parse the IPs. All I had to do was supply a file formatted properly (no spaced in between the dash) and boom, each possible IP was spit out:
Man, I totally didn't realize that iptools would do that out of the box.
