Trying to work on a Cisco case study.

Most routers and switches support the first 255 connections, using a MASK of 255.255.255.0.

Actually, it depends on the equipment in use. I have routers that have more than 190K route prefixes in their route tables.
Most intelligent switches can be partioned into VLANS, or Virtual LANS. Each VLAN is a seperate layer 3 network (aka Broadcast Domain). Different switches can support a differing number of VLANS. Some high end ($100K plus) switches support thousands of VLANS in a switch. The most I've ever had in a single switch is about 90.
Some routers support 802.1Q vlan tagging on traffic so that you can use one interface for multiple networks. Others support "secondary addressing" on an interface that lets you bind multiple IP networks to a single physical interface.
The user that said you could only have 256 nodes in an ethernet network is incorrect. In a large enterprise network, it's not unusual to have 3-400 nodes in a single, switched ethernet segment. The limitation is not one of IP, or ethernet really, but of broadcasts generated by higher level protocols (Netbios, IPX, Apple Chooser, etc).
I've had customers with token ring (aka choken ring aka broken ring) networks that had 200 nodes per ring. I don't reccommend ring sizes that large at all.

DarthSabbath is correct. The other two don't know what they're talking about. Give him the points.
Well, seems like "enochiansorcerer" likes to send off-line insults but doesn't have the smarts (or guts, not sure which) to enable e-mails to be sent to him. So, in the interest of fairness, I'll post his comment and my response below:

Message: I always wondered what an idiot looked likel, now that i've seen you, I know...Thanks
And now my response:
Really? Based on what? Your comment that "256 nodes is the limit on an ethernet network" makes me think you are looking in the mirror when you call ME an idiot. Would you mind explaining the 790+ node network that I'm connected to right now, please?
Please know what you are talking about when you call someone an idiot!
Good day, all!

Switches only support one network... they just divide the network into different collision domains. Routers support one network for each interface (for example... 2 ethernet interfaces connected to a switch that leads to the workstations, and 2 serial interfaces connected to other routers... each one can be a different network)
