    I have a switch into which I have many devices. runs DHCP. I also have two routers plugged in on DHCP on with WAN into the switch and the other on DHCP on with WAN into the switch. Both function fine. There seems to be a grey area on if I could set both routers to Some say yes if they are on "different floors" I take this to mean that they would have to be on different switches? Some say no it can't be done. Some say sometimes it will work with both routers on and sometimes not.

    This leads me to my question which is an Internet Service Provider has probably 50 different customers all with their DSL routers set to the same private ip of which is so common. Why is not OK for me to use two's but it's OK for an internet service provider to use for 50 different customers? Do they have different hardware than I do or what technologies might they employ to use route traffic to the same private range on so many different networks.

    Thanks in advance...
