# Breaking down network range to individual networks

```Hello,

Does anyone know about a feature of ipaddress that will take the following
network range:

"10.224.16.0-10.224.23.0"

and convert it to individual networks?

I am trying to figure out the best way to take a network range and break it
up into the largest possible networks.

I started working out some things on paper but I don't want to get too far
ahead of myself in case there is a function or easy way that already does
this.

Pasted some brainstorming below to show that I am actively working this and

10.224.23.0/24'))
IPv4Network

IPv4Network('10.224.16.0/24').compare_networks(IPv4Network('10.224.23.0/24')
)

0.0.x=0.0
/24 x + 0
/23 x + 1 = 0.0.0.0
/22 x + 3 = 0.0.0.0

1  can be /18 if x = 0
2  can be /19 if x = 0, 32
4  can be /20 if x = 0, 16, 32, 48
8  can be /21 if x = 0, 8, 16, 24, 32, 40, 48, 56
16 can be /22 if x = 0, 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48, 52,
56, 60
32 can be /23 if x = 0 through 62

64 can be /24 if x = 0 though 255

10.224.255.0
