DHCP Server Operation

Host

host hostname { [ parameters ] [ declarations ]

}

There must be at least one host statement for every BOOTP client that is to be served. Host statements may also be specified for DHCP clients, although this is not required unless booting is only enabled for known hosts. If it is desirable to be able to boot a DHCP or BOOTP client on more than one subnet with fixed addresses, more than one address may be

specified in theparameter, or more than one host statement may be specified. If client-specific boot parameters must change based on the network to which the client is attached, then multiple host statements should be used. If a client is to be booted using a fixed address if it’s possible, but should be allocated a dynamic address otherwise, then a host statement must be specified without a fixed-addressclause. hostname should be a name identifying the host. If a hostname option is not specified for the host, hostname is used. Host declarations are matched to actual DHCP or

BOOTP clients by matching theoption specified in the host declaration to the one supplied by the client, or, if the host declaration

or the client does not provide aoption, by matching the hardware parameter in the host declaration to the network hardware address supplied by the client. BOOTP clients do not normally provide a

r, so the hardware address must be used for all clients that may boot using the BOOTP protocol.

Group

group { [ parameters ] [ declarations ] }

The group statement is used simply to apply one or more parameters to a group of declarations.

It can be used to group hosts, shared networks, subnets, or even other groups.

8.4.3 ALLOW and DENY

The allow and deny statements can be used to control the behaviour of the DHCP server in response to various sorts of requests.
