How to use the ip.isEqual function in ip

  // check ip1
  if (!(ip.isV4Format(ip1) || ip.isV6Format(ip1))) {
    throw new Error('invalid argument: ip1 in ipMatch() function is not an IP address.');
  }
  // check ip2
  const cidrParts: string[] = ip2.split('/');
  if (cidrParts.length === 2) {
    return ip.cidrSubnet(ip2).contains(ip1);
  } else {
    if (!(ip.isV4Format(ip2) || ip.isV6Format(ip2))) {
      console.log(ip2);
      throw new Error('invalid argument: ip2 in ipMatch() function is not an IP address.');
    }
    return ip.isEqual(ip1, ip2);
  }
}
