configured as described in RFC 1001/1002. The value is specified as a single octet which identifies
the client type. A value of 1 corresponds to a NetBIOS B-node; a value of 2 corresponds to a P-node;
a value of 4 corresponds to an M-node; a value of 8 corresponds to an H-node.

option netbios-scope

strin

g;

The NetBIOS scope option specifies the NetBIOS over TCP/IP scope parameter for the client as
specified in RFC 1001/1002. See RFC1001, RFC1002, and RFC1035 for character-set restrictions.

option font-servers

ip-address [, ip-address ...

];

This option specifies a list of X Window System Font servers available to the client. Servers should
be listed in order of preference.

option x-display-manager

ip-address [, ip-address ...

];

This option specifies a list of systems that are running the X Window System Display Manager and
are available to the client. Addresses should be listed in order of preference.

option dhcp-client-identifier

data-strin

g;

This option can be used to specify a DHCP client identifier in a host declaration, so that DHCP can
find the host record by matching against the client identifier. (Also used by the client in a

“send

dhcp-client-identifie

r” declaration to supply its identifier to the server)
