The IP Address format is up to 42 ASCII characters including a terminating NULL character. The first byte in the array is the left most character in the string as written. For
example: If the IP Address is 423.156.78.012, the first byte is the ASCII character “4”. If the MSG destination is an INTERCHANGE client on a host computer, the destination
is specified as “client” and stored as a NULL terminated string.
