How to get the IP prefix while we have subnet and IPv4 address using python-netaddr?

Question

I am using python-netaddr library to work on IP Addresses and subnets. I read the full documentaion of netaddrd given: Netaddr documentation. But didn't found any solution to my problem. I have a IP Address and subnet i want to get prefix for that ip by using both of them. So that i can print all of the ip coming into the subnet. For example: ``` Ip Address: 192.0.2.0 Subnet Network: 255.255.255.0 It should return the prefix which is : 24 ```

Accepted Answer

To get 24 you can use the following snippet

```
ip = IPNetwork('192.0.2.0/255.255.255.0')
print ip.prefixlen
```

But if you want list of all addresses in the subnet it's easier to use:

```
ip = IPNetwork('192.0.2.0/255.255.255.0')
list(ip)
```
