[Tutor] dynamical program to create subnets CIDR

[ose micah]

Hello All,
Can anyone help with a program that could compare a list of IPs and create the least possible CIDR block sets from these IPs.
for example.
I have a list say:
202.238.149.0/22202.238.164.0/22202.238.168.0/23202.238.176.0/20202.238.174.0/23202.238.172.0/2320.226.12.224/2720.223.14.0/2410.32.0.0/1510.35.0.0/1610.54.63.128/2610.59.250.0/2610.224.0.0/2410.228.69.0/24
I want to reduce this list to:
10.32.0.0/14202.238.149.0/19
10.224.0.0/1310.54.63.0/13

Thanks
