Let's say you have a small network (50-60 IPs) and assign everything a 10.x.x.x IP with a subnet of 255.0.0.0. This gives you a huge range of usable IPs. What performance implications will this have on the network if any? For one, you're leaving yourself wide open to ARP attacks and resource exhaustion on your edge router. A /8 subnet can potentially ...

This is a very common situation and unfortunately the initial response should not be technical. Inter-Vlan routing is fine if it works for your company. Yes there are possible security and performance issues but do you have the staff to manage the requirements if you lock your systems down? As long as you have designed your network properly you should be ...

ANSWER: In the above configuration the switches in the design are functioning as layer two switches, not layer three. In the simplest implementation they are not performing any Layer 3 tasks, though in some circumstances there might be useful Layer 3 features you might want to implement depending on the specific design. Some of those features might require ...

It's 256 -2. The fact that the switches exist doesn't reduce the number of available ip addresses. The switches don't require ip addresses. If you did assign them ip addresses then that would be subtracted from the 254. If you assign an ip address to the switches then that reduces the number of remaining available ip addresses, just as it does when ...

If correctly configured then there's no actual L3 routing going on here - only L2 switching, so they wouldn't need IP interfaces (well other than for management obviously), but you don't provide enough information to speak about the specifics of this setup.

Like this: 10.6.0.0/24 10.6.1.0/24 10.6.2.0/24 10.6.3.0/24 10.6.4.0/24 10.6.5.0/24 10.6.6.0/24 10.6.7.0/24 10.6.8.0/24 10.6.9.0/24 10.6.10.0/24 10.6.11.0/24 10.6.12.0/24 ... 10.6.254.0/24 each /24 can hold 250+ hosts plus gateway address and broadcast address.

I'd approach this in a totally different way: Configure a PC (laptop) with 3 IP addresses: 192.168.213.250 and 10.0.4.250 and an address on the new subnet. connect the two devices and the laptop on the same VLAN. (no firewall, just (an isolated) hub/switch or direct connect cable) just connect to the old IP adres and start reconfiguring. Then change your ...
