Returns True, if "Value" is a valid IPv6 address. Cannot be a symbolic Name!

function IPToID(Host: string): Ansistring;

Returns a string with the "Host" ip address converted to binary form.

function StrToIp6(value: string): TIp6Bytes;

Convert IPv6 address from their string form to binary byte array.

function Ip6ToStr(value: TIp6Bytes): string;

Convert IPv6 address from binary byte array to string form.

function StrToIp(value: string): integer;

Convert IPv4 address from their string form to binary.

function IpToStr(value: integer): string;
