blockList.check(address[, type])


如果给定的 IP 地址与添加到 BlockList 的任何规则匹配,则返回 true

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

// IPv4 地址的 IPv6 表示法有效:
console.log(blockList.check('::ffff:7b7b:7b7b', 'ipv6')); // 打印: true
console.log(blockList.check('::ffff:123.123.123.123', 'ipv6')); // 打印: 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
