global parameter or not ?

[Glenn Satchell]

Setting dynamic dns in only one subnet is usually done like this:

# global scope, disable ddns updates
ddns-update-style interim;
ddns-updates no;

subnet .... {
     # enable ddns updates in this scope
     ddns-updates yes;
     ....
}
subnet ... {
     # no dynamic dns here, inherited from global
     ....
}

Or you could do the opposite, enable ddns-updates at the global level 
and turn it off in selected subnets. Whichever one is easier for you.
