specified in theparameter, or more than one host statement may be specified. If
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
