blockList.check(address[, type])

• address <string> | <net.SocketAddress> 要检查的 IP 地址
• type <string> 可以是 'ipv4' 或 'ipv6'。默认值: 'ipv4'。
• 返回：<boolean>

如果给定的 IP 地址与添加到 BlockList 的任意规则匹配，则返回 true。

【Returns true if the given IP address matches any of the rules added to the BlockList.】

const blockList = new net.BlockList();
blockList.addAddress('123.123.123.123');
blockList.addRange('10.0.0.1', '10.0.0.10');
blockList.addSubnet('8592:757c:efae:4e45::', 64, 'ipv6');

console.log(blockList.check('123.123.123.123'));  // Prints: true
console.log(blockList.check('10.0.0.3'));  // Prints: true
console.log(blockList.check('222.111.111.222'));  // Prints: false

// IPv6 notation for IPv4 addresses works:
console.log(blockList.check('::ffff:7b7b:7b7b', 'ipv6')); // Prints: true
console.log(blockList.check('::ffff:123.123.123.123', 'ipv6')); // Prints: true 拷贝
