How can I block DHCP clients from accessing the Internet but leave the
static
IP clients accessible?
As LanWench says this is NOT a DNS "thing".
The following is a FAKE solution:
You can use DNS to pretend to solve this problem
perhaps but it will not be a true solution. Just setup
a DNS server to be use ONLY for the DHCP clients
and don't allow it to resolve any Internet names.
But there are so many better (and more reliable)
ways to do it.
You could just as easily just give the DHCP clients
a BOGUS "Default Gateway" as long as you are
willing to setup one of those OR if you only have ONE
subnet for the DHCP clients (they don't need to reach
ANY real routers/gateways.)
But the best solutions involve some type of firewall
which can actually CONTROL access by IP and then
you make sure the DHCP clients get a range of IP
addresses that is blocked at the Firewall.
Most real (read: successful) solutions are going to
use this method or an advanced version of it.
