Hello,

I am new to a local ISP, and am researching best practices for DHCP in an
ISP setting. Specifically, what is the best way to setup DHCP for clients?

Their current solution is a class straight class C with lots of users, but
when browseing the network, users can see other computers under workgroup.

Are you using W2000 as your DHCP server at an ISP? That sounds unusual to
me.
Most providers either assign one static IP (or many) and a local
device/router that does NAT to a private nonroutable IP range, and DHCP, or
leave it up to the end user/client to provide something that does that, and
simply provide the public IP address(es).
How is your company doing this now?
 
My ISP use "host routing" where the subnet mask is 255.255.255.255. That
means every connection is routed, so no broadcast traffic or seeing other
peoples computers.

Currently the router hosts DHCP, with a class C subnet (private IP) DHCP'd
out to the customers. There are less than 200 customers on this segment, but
will soon cause problems.

The 255.255.255.255 could work, except I don't want to create a DHCP pool
for each IP address.
