Using prefix returns wrong ip range.

[mustafaKagan]

Describe the bug
Using prefix returns wrong ip range. Normarlly I give to prefix function network like 8.8.8.8/24 ,I expect to see 8.8.8.0-8.8.8.255 ip pool but function returns 8.8.8.8-8.8.9.7

To Reproduce
Steps to reproduce the behavior:

1. let prefix=new Ip.Prefix("8.8.8.8",24)
2. prefix.lastIp().toString() ;//"8.8.9.7"

Expected behavior

1. let prefix=new Ip.Prefix("8.8.8.8",24)
2. prefix.lastIp().toString() ;//"8.8.8.255"

@mustafaKagan thanks for reaching out.

For performance reasons the Prefix constructor doesn't automatically check for bit boundary correctness, that's why you get those results on 8.8.8.8/24, which is invalid CIDR technically.
But, you can always force the correction after creation by running:

const prefix = (new Ip.Prefix("8.8.8.8",24)).correctBitBoundary();
prefix.lastIp().toString(); // "8.8.8.255"
