+
+ The ip-address data type can be entered either as an
+ explicit IP address (e.g., 239.254.197.10) or as a domain
+ name (e.g., haagen.isc.org). When entering a domain name,
+ be sure that that domain name resolves to a single IP
+ address.
+
+ The int32 data type specifies a signed 32-bit integer.
+ The uint32 data type specifies an unsigned 32-bit integer.
+ The int16 and uint16 data types specify signed and
+ unsigned 16-bit integers. The int8 and uint8 data types
+ specify signed and unsigned 8-bit integers. Unsigned
+ 8-bit integers are also sometimes referred to as octets.
+
+ The string data type specifies an NVT ASCII string, which
+ must be enclosed in double quotes - for example, to spec-
+ ify a domain-name option, the syntax would be

+ string enclosed in double quotes, or a series of octets
+ specified in hexadecimal, seperated by colons. For exam-
+ ple:

+ option client-identifier "CLIENT-FOO"
