Assign static IP by Option 82 agent.remote-id

Mon Jan 4 10:41:41 UTC 2010

Hi Billy

subclasses are covered in the dhcpd.conf man page, but something like
this:

class "static-option-82" { match option agent.remote-id; }

subclass "static-option-82" "VP123456";

Repeat the subclass statement for each port/host as required. Then in
the pool for dynamic allocation put

pool {
    range 192.168.10.20 192.168.10.55;
    deny dynamic bootp clients;
    deny members of "static-option-82";
}

You need to keep the Static-1 class and individual pool that you
currently have to give each option 82 host a specific IP address. The
static-option-82 class makes the deny part simpler, that's all.

regards,
-glenn
