DHCP hostname

호스트 이름을 지정을 해줄순 있는데 MAC 주소에 따라서 설정을 해야 해서 서버댓수가 많으면 무지 귀찮을 수도?

The use-host-decl-names statement
use-host-decl-names flag;
If the use-host-decl-names parameter is true in a given scope, then for every host declaration within that scope, the name provided for the host declaration will be supplied to the client as its hostname. So, for example,

    group {
      use-host-decl-names on;

     host joe {
        hardware ethernet 08:00:2b:4c:29:32;
fixed-address joe.fugue.com;
      }
    }

is equivalent to

     host joe {
        hardware ethernet 08:00:2b:4c:29:32;
fixed-address joe.fugue.com;
        option host-name "joe";
      }
An option host-name statement within a host declaration will override the use of the name in the host declaration.
It should be noted here that most DHCP clients completely ignore the host-name option sent by the DHCP server, and there is no way to configure them not to do this. So you generally have a choice of either not having any hostname to client IP address mapping that the client will recognize, or doing DNS updates. It is beyond the scope of this document to describe how to make this determination.
