Can I export the IP list?

Yes, you can copy the generated IP list or export it in various formats including plain text, CSV, and JSON for use in other network tools.

Python:

import ipaddress

def expand_cidr(cidr):
    network = ipaddress.IPv4Network(cidr, strict=False)
    return [str(ip) for ip in network.hosts()]

def expand_cidr_all(cidr):
    network = ipaddress.IPv4Network(cidr, strict=False)
    return [str(ip) for ip in network]

# Example usage
cidr = "192.168.1.0/24"
host_ips = expand_cidr(cidr)
all_ips = expand_cidr_all(cidr)
            

JavaScript:

function expandCIDR(cidr) {
    const [ip, prefix] = cidr.split('/');
    const prefixNum = parseInt(prefix);
    const hostBits = 32 - prefixNum;
    const numIPs = Math.pow(2, hostBits);
    
    const ipNum = ip.split('.').reduce((acc, octet) => 
        (acc << 8) + parseInt(octet), 0);
    
    const networkIP = ipNum & (~(numIPs - 1));
    const ips = [];
    
    for (let i = 0; i < numIPs; i++) {
        const currentIP = networkIP + i;
        const octets = [
            (currentIP >>> 24) & 255,
            (currentIP >>> 16) & 255,
            (currentIP >>> 8) & 255,
            currentIP & 255
        ];
        ips.push(octets.join('.'));
    }
    return ips;
}
