When configuring dhcpd 8 or dhclient 8options must often be declared. The syntax for declaring options, and the names and formats of the options that can be declared, are documented here. DHCP option statements always start with the option keyword, followed by an option name, followed by option data.

The option names and data formats are described below. It is not necessary to exhaustively specify all DHCP options - only those options which are needed by clients must be specified. Option data comes in a variety of formats, as defined below:. The ip-address data type can be entered either as an explicit IP address e. When entering a domain name, be sure that that domain name resolves to a single IP address.

Additionally, please note the software dhcpd or dhclient will only attempt to resolve the domain name the first time the option is needed. For example, if the next-server option is defined as a domain name, dhcpd will attempt to resolve it while responding to the first client query dhcpd receives after startup. The ip6-address data specifies an IPv6 address, like or 3ffe:bbbb:aaaa:aaaa The int32 data type specifies a signed bit integer.

The uint32 data type specifies an unsigned bit integer.

The int16 and uint16 data types specify signed and unsigned 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 text data type specifies an NVT ASCII string, which must be enclosed in double quotes - for example, to specify a root-path option, the syntax would be.

The domain-name data type specifies a domain name, which must not be enclosed in double quotes. The domain name is stored just as if it were a text option.

The domain-list data type specifies a list of domain names, enclosed in double quotes and separated by commas "example. The flag data type specifies a boolean value. Booleans can be either true or false or on or off, if that makes more sense to you. The string data type specifies either an NVT ASCII string enclosed in double quotes, or a series of octets specified in hexadecimal, separated by colons. For example:. To do this, you can use expression evaluation.

The dhcp-eval 5 manual page describes how to write expressions. To assign the result of an evaluation to an option, define the option as follows:.

There is no such limitation on teh windows server and hence the correct procedure is to define option 60 first.

Inside option 43we can have encapsulated vendor-specific sub-option codes between 0 and Vendors can define these sub-options as per their wish.

Maybe a good point for a feature request. If you have the value for Option 60 for each device, you can start to use them. After that, you just need to define a new policy for the scope.
