Hello, This is a followon from a previous question. I have two separate Domains over a Split site and through the advice from experts on this site i have decided to restucture creating one Domain to serve them all. By doing so I will be Hosting over 700 network devices over the same subnet. The recommended limit is around 400. My plan is to Vlan or Subnet the network at a later stage, 8 weeks to be precise when my new core switching gear arrives. Till then I need to know if there is going to be any significant reduction in the quality of Network traffic over the subnet. At present the network runs at 100mb with the servers pluged into a 10gb core.

Many Thanks, Aelara.

What is a "split site"?

If the devices are already all connected to the same VLAN/broadcast domain then there should be no significant performance degredation.

If the devices are currently segregated, then I'd suggest waiting until the new equipment arrives.

10.1.4.0/22 OR 10.1.4.0 255.255.252.0

gives 10.1.4.1 - 10.1.7.254

reserve 10.1.4.255, 10.1.5.0, 10.1.5.255, 10.1.6.1, 10.1.6.255, and 10.1.7.1 as the network and broadcast addresses for future subneting.  This leaves you with 1016 usable addresses

10.1.8.0/21 OR 10.1.8.0 255.255.248.0 with the same reservations will give 2032 usable addresses
