Subnet
A library to create IPv4 subnetworks based on a given address and the number of hosts you want to connect.
✏️ Usage
use std::net::Ipv4Addr;
use subnet::{self, SubnetData, SubnetError};
fn main() {
let addrs: Ipv4Addr = Ipv4Addr::new(192, 168, 20, 0);
let hosts: u32 = 120;
let subnet: SubnetData = subnet::create_subnet(addrs, hosts).unwrap_or_else(|err: SubnetError| {
println!("Error: {}", err);
std::process::exit(1);
});
let useful_range: Vec<Ipv4Addr> = subnet.useful_range();
let bin_subnet: String = subnet::ip_to_binary(subnet.subnet_addrs());
println!(
"Subnet address: {}\nBin subnet: {}\nBroadcast: {}\nMask: /{}\nUseful range: [{} - {}]",
subnet.subnet_addrs(), bin_subnet, subnet.broadcast(), subnet.mask(),
useful_range.first().unwrap(), useful_range.last().unwrap()
);
}
Output
Subnet address: 192.168.20.0
Bin subnet: 11000000101010000001010000000000
Broadcast: 192.168.20.127
Mask: /25
Useful range: [192.168.20.1 - 192.168.20.126]
