The domain name is irrelevant - it does NOT affect your addressing structure

That's one way to do it, or you can just use the same domain name statement in each one. YOu can omit ddns-rev-domainname as it works out of the box with defaults - you only need to specify it if doing things like bodging around doing dynamic DNS on a reverse zone that's not on a /24 boundary.


subnet 10.57.46.0 netmask 255.255.255.0 {
     ddns-domainname = "dai.wadsworth.org";
...
}

subnet 10.57.47.0 netmask 255.255.255.0 {
     ddns-domainname = "dai.wadsworth.org";
...
}

subnet 10.57.48.0 netmask 255.255.255.0 {
     ddns-domainname = "dai.wadsworth.org";
...
}

and so on

it really is that simple !


BTW - you have a few redundancies in your config :

      option domain-name-servers admin.wadsworth.org, bionsc.wadsworth.org, ldap1.wadsworth.org, 10.50.156.21;
       pool {
             range 10.57.46.30  10.57.46.225;
             allow unknown-clients;
             allow known-clients;
             option domain-name-servers admin.wadsworth.org, bionsc.wadsworth.org, ldap1.wadsworth.org, 10.50.156.21;

You've duplicated domain-name-servers and your allow statements (unless you have something at a higher inheritance level to override) simply implement the defaults.
