API

  • isIPv4(input: string): boolean

    Returns true if input is a version 4 IP address, otherwise returns false. It should be compatible with Node.js' net.isIPv4.

  • isIPv6(input: string): boolean

    Returns true if input is a version 6 IP address, otherwise returns false. It should be compatible with Node.js' net.isIPv6.

  • isIP(input: string): number

    Tests if input is an IP address. Returns 0 for invalid strings, returns 4 for IP version 4 addresses, and returns 6 for IP version 6 addresses. It should be compatible with Node.js' net.isIP.

Any incompatibility, please check net_isip_test.ts
