Windows 7: IP addresses with switches installed

IP addresses with switches installed

Lets say I have a computer at my desk, it's IP is 192.168.0.2.
If I install a 4 port switch (between my cable modem/router and the computer), would the switch now be 192.168.0.2 and the ports be 192.168.0.3(4,5,6)?

When it's not a managed switch, which I assume you are talking about, the router would be handling the IP assignments with DHCP.

The IP assignments would be at the router's discretion typically 192.168.x.2/254 which varies depending on the router unless you set up static IP's by using IPv4 properties or use the DHCP reservation in the routers settings which to me is the easiest way.

You would need a later 3 switch for DHCP functions since IP addresses operate at layer 3 of the OSI model

The switch will have a management IP address that is different from the hosts connected. It will only be used for Telnet or management purposes of the switch if it is a managed one. I would follow chev65's advice on creating a DHCP reservation on the router for the static IP address that will be assigned to that switch

I'm using DHCP at the router, the switch is unmanaged. I was wondering if the switch got an IP address from the router. Would I see the actual switch in "Network and Sharing Center"?

If it is unmanaged then it shouldn't receive an IP address since it is just a layer 2 device. Though don't hold that against me since I have personally used unmanaged switches other than those integrated in routers.

As for showing in networking and sharing centre. The map is based on IP addresses and MAC addresses. It should show up there though since it is unmanaged it may not.

An unmanaged switch doesn't have an IP address. In fact it doesn't even have any concept of what an IP address is. It operates only at the MAC address level.
