[GLLUG] default addresses, gateways, large networks

[Lachniet, Mark]

If its on a different physical network, probably not.  Getting IP conflicts is usually due to problems with ARP on the same LAN, so it would have to be on the same broadcast domain for it to block one of the devices IP addresses. 

It might, however, cause problems with other devices that are connected to both of the networks, like a core switch that sees 192.168.1.1 on more than one VLAN simultaneously or something...

That said there are probably some circumstances where some unanticipated event could prove me totally wrong and hork you up royally :)

question?
 a router has a default IP address of 192.168.1.1/24. you are
installing on a large network. you are going to configure it to be
192.168.20.5/24  it has been pre-connected to the network. but not
turned on. If there is a pingable gateway upstream (not yet WAN) of
192.168.1.1/24 will it cause a conflict when turned on if still
connected to the network (does not run a dhcp server). It will have to
go through other routers first.
