setup different network IP address
Dear experts,
I wish to obtain some information about network setup when there are different IP ranges.
What is proper way to setup IP ranges 192.168.1.x, 192.168.2.x, 192.168.3.x, all the way up to 192.168.10.x
1. do I need or is it better to separate switches for each of the IP range?
2. do I configure the IP range in firewall/router or in switches?
3. If I specify each port on my firewall for each of the IP range and connect all ports to the back of a 48 port switch what will happen?
- will the network devices obtain the IP from any of those ranges as in 192.168.1.x to 192.168.10.x?
- does the assigning of the IP depends on the DNS server? (if the DNS server is on 192.168.1.x then all network devices will be assigned to 192.168.1.x)
4. any additional references for network information will be great. Thanks

Really, it all depends on the mask, and what you're actually trying to accomplish. So can you explain why you want to have the separate network ranges? Do you want them to be able to communicate with each other? (e.g. Do you want 192.168.1.5 to be able to reach 192.168.7.35?) Do you need to keep some of those devices from communicating with others?
What are you trying to accomplish?

Hi Doughboy,
Yes I may want them to communicate with one another. For example, I am setting up the subnet range of 192.168.1.x for all company workstations, file servers, sql servers, DSN/AD, etc....., subnet range of 192.168.7.x for my IP cameras, subnet range of 192.168.5.x for my IP phones. I have a PC installed with IP Camera softwares and I wish to retrieve those backup data from time to time from subnet 192.168.1.x.
Do you have any suggestions? Thanks

What is the goal to separate the networks, and how many devices are we talking about.
But based on the initial questions, and I will just assume we are working with Cisco switches although most HP, Juniper or Cisco switches will have the feaures.
1. No need to separate the physical hardware, you will be using VLANS to set this up with access ports and trunk ports.
2. This depends on the firewall, but the router the router will need a sub interface on each network so they can communicate. Your firewall may need this as well depending on how you connect your network and use nat
3. Do you mean switch, then yes you specify their vlan
- You endpoint can get IP addresses for each VLAN, in cisco this is an IP helper address and sites and services in AD along with the setup in DHCP will allow the DHCP server to issue IP addresses for each subnet. Basically the router will forward the DHCP packet to the server with the source interface address so DHCP knows to respond with an IP from that subnet.
- No, DHCP and AD. DNS can be supplied to an endpoint via DHCP.
4. Big topic, try googling VLAN setup and DHCP multiple subnets for more info.
