Option value

This field defines the contents of the DHCP option. IP addresses are normally specified using the conventional IPv4 notation, e.g. 123.123.123.100. Integer tapes are usually entered in decimal digits and string types as simple text. Multiple values in a single field are separated with commas, e.g.123.123.123.100, 123.123.123.200.

Note: The maximum possible length value depends on the selected option number. RFC 2132 lists the maximum length allowed for each option.
