If router R1 is PC's default gateway, when PC first tries to contact Google, PC will send data to R1 (as PC knows Google's IP-address is not in PC's subnet), However R1 will tell the PC that a more appropriate route to 64.20.60.99 is via router R2.

An IP address with subnet mask 255.255.255.0; We have several computers, and are wanting to set up a simple LAN, all with internet access. Given that our 'wan' cable is an RJ45 Ethernet cable, is it possible to use a normal home router, and plug in all the computers alongside the 'internet' cable into the router's switch ports?

Mar 10, 2015 · Router> enable Router# configure terminal Router(config)# interface fastethernet 4 Router(config-int)# ip address 192.0.2.1 255.255.255.0 Router(config-int)# no shutdown Router(config-int)# exit If you want to know about how all the information is aggregated and shared between LIR's, then you need to read up on AS Numbers and the BGP protocol.

Of course, you'll need to add a second router ip address on the same interface (192.168.2.1 in the example above) since the class C netmask (255.255.255.0) prevents 192.168.1.x subnet hosts from seeing the 192.168.2.x subnet hosts and vice-versa - …

If your computers were all in the 192.168.1.0/24 network and 10.10.10.1 was the ip address of the interface on the middle router connected to the left most router. The left most router would need an IP like 10.10.10.2. Then the middle router would probably have 192.168.1.1 on the interface connected to the switch.

Jun 10, 2009 · If you are using Windows Server DHCP, then the DHCP viewer shows the used IP addresses. Maybe you have a very small range of IP, try extending the range. I had a similar issue when using router to assign IP addresses. My solution, I extended the range and that seemed to work.

Aug 15, 2009 · An IP router has to have a minimum of 2 IP addresses, because its function is deciding on where to send the packet next. A minimal configuration of TCP/IP network where you need a router is a connection between two networks …

Oct 31, 2010 · For instance, in a home scenario (which I know isn't directly relevant, since you've tagged this with 'cisco') you'd better have a very good reason to not use 192.168.1.1/24 or 192.168.1.254/24 as the router IP address, and 'admin'/'admin' as the username and password for router administration.

IP forwarding should be enabled when you want the system to act as a router, that is transfer IP packets from one network to another. In the simplest case, consider a server with two physical ethernet ports which is meant to connect to two different networks (say your internal network and the outside world as provided by a DSL modem).

This will, almost certainly, be an IP address on an interface of a local router. However, it may not be an address on which you can manage the router. If this is for a "home-type network", the inside IP (your default gateway) and the management address will probably be one and the same, but in a "large/corporate-type network" I wouldn't be so sure.
