Ip

The Ip module supports both the IPv4 and IPv6 addresses. By default, they are represented as binary strings of 4 and 16 bytes, respectively.

List of functions

• Ip::FromString(String{Flags:AutoMap}) -> String? - From a human-readable representation to a binary representation.
• Ip::SubnetFromString(String{Flags:AutoMap}) -> String? - From a human-readable representation of subnet to a binary representation.
• Ip::ToString(String{Flags:AutoMap}) -> String? - From a binary representation to a human-readable representation.
• Ip::SubnetToString(String{Flags:AutoMap}) -> String? - From a binary representation of subnet to a human-readable representation.
• Ip::IsIPv4(String?) -> Bool
• Ip::IsIPv6(String?) -> Bool
• Ip::IsEmbeddedIPv4(String?) -> Bool
• Ip::ConvertToIPv6(String{Flags:AutoMap}) -> String: IPv6 remains unchanged, and IPv4 becomes embedded in IPv6
• Ip::GetSubnet(String{Flags:AutoMap}, [Uint8?]) -> String: The second argument is the subnet size, by default it's 24 for IPv4 and 64 for IPv6
• Ip::GetSubnetByMask(String{Flags:AutoMap}, String{Flags:AutoMap}) -> String: The first argument is the base address, the second argument is the bit mask of a desired subnet.
• Ip::SubnetMatch(String{Flags:AutoMap}, String{Flags:AutoMap}) -> Bool: The first argument is a subnet, the second argument is a subnet or an address.

Examples

SELECT Ip::IsEmbeddedIPv4(
  Ip::FromString("::ffff:77.75.155.3")
); -- true

SELECT
  Ip::ToString(
    Ip::GetSubnet(
      Ip::FromString("213.180.193.3")
    )
  ); -- "213.180.193.0"

SELECT
  Ip::SubnetMatch(
    Ip::SubnetFromString("192.168.0.1/16"),
    Ip::FromString("192.168.1.14"),
  ); -- true

SELECT
  Ip::ToString(
    Ip::GetSubnetByMask(
      Ip::FromString("192.168.0.1"),
      Ip::FromString("255.255.0.0")
    )
  ); -- "192.168.0.0"
