G+_Bostjan Cadej Posted January 27, 2015 Share Posted January 27, 2015 In your last KH show you briefly talked about internal network setup. You also mentioned ( ) that you'll talk in more details in one of your next shows. I hope you can answer my question in that episode. In my small office soon there will be more than 256 devices connected to the network. How to setup my network so that all devices can be connected to same network and talk to each other? How to setup my network and assign IPs, when there will be more than 256 devices. So devices will not be able to get 192.168.1.xxx IP. Will devices be able to talk to each other? And on the flip side how can I setup my network with just IP management, so that devices can not talk to each other (at least directly not)? Can you please give me a quick overview how to setup internal network if there are 257 devices? If there are 10 000 devices? If there are (in theory) 256x256+1 devices in the network? Thanks.

G+_Reed Hanson Posted January 27, 2015 Share Posted January 27, 2015 Is there a way to assign an IP to a certain switch, and all the devices on that switch run off that IP, or would that not work? Noob at networking, so I don't know all the ins and outs :) Link to comment Share on other sites More sharing options...

G+_Stede Bonnett Posted January 30, 2015 Share Posted January 30, 2015 If your router can handle it you can go to a larger IP space. I use pfSense at work with 172.16.0.0/16 (I inherited the network as 172.16.1.0/24 so switching was pretty easy). The 172.16 -> 172.31 space are non-routable "ClassB" ranges like 192.168.0 -> 192.168.255 are "ClassC". You will have to keep an eye on your switches though, some may only be able to track a few thousand MAC addresses per port. If you want to isolate some machines (I have my IP cameras on their own 192.168.x.0/24 and in a VLAN for good measure) you can add physical/virtual/VLAN interfaces to your router and control traffic between them.

G+_Bostjan Cadej Posted January 30, 2015 Author Share Posted January 30, 2015 What about 10.0.0.0 -> 10.255 IP range? Link to comment Share on other sites More sharing options...
G+_Mat Murdock Posted January 30, 2015 Share Posted January 30, 2015 If you want a more powerful firewall look at PFsense. It will do what you want. Link to comment Share on other sites More sharing options...
G+_Bostjan Cadej Posted January 30, 2015 Author Share Posted January 30, 2015 I was wondering of how to setup network. Subnetting and stuff. Pfsense wouldn helped me with that. :( Link to comment Share on other sites More sharing options...
G+_Joe Morrison Posted January 30, 2015 Share Posted January 30, 2015 You can use the 10.x.x.x Range but I would keep the range smaller something like this should work. Network Address: 10.0.0.0/23 Netmask: 255.255.254.0=23 Wildcard: 0.0.1.255 HostMin: 10.0.0.1 HostMax: 10.0.1.254 Broadcast: 10.0.1.255 Hosts/Net: 510 Private Link to comment Share on other sites More sharing options...
G+_Joe Morrison Posted January 30, 2015 Share Posted January 30, 2015 If you really need 513 hosts then you'd need to bump it up to this... Network Address: 10.0.0.0 /22 Netmask: 255.255.252.0=22 Wildcard: 0.0.3.255 HostMin: 10.0.0.1 HostMax: 10.0.3.254 Broadcast: 10.0.3.255 Hosts/Net: 1022 Link to comment Share on other sites More sharing options...
