Does each subnet need a router?

You don’t need a router. If you set the subnet mask on all of the PCs to be 255.255. 0.0, then they should all be able to ping each other. Basically, opening up the subnet mask puts all of the PCs on the same subnet, so a router isn’t needed.

CAN devices on the same subnet communicate?

A subnet is just a range of IP addresses. All the devices in the same subnet can communicate directly with one another without going through any routers. In IPv4, a network interface is connected to only one subnet and has only one IP address. 101.15 and my subnet mask is 255.255.

Do the hosts require an IP router to communicate with each other?

Since there are no Routers in this illustration, we know all the communication is happening within the same network — therefore, Host A and Host B are both configured with IP addresses that belong to the same network. Since each host is also a L3 device, they each also have an ARP Table. …

How do I communicate with two IP addresses?

Open Network (and Dial-up) Connections. Click Properties. Click Internet Protocol (TCP/IP) then click Properties. Click Advanced. Type in the new IP address then click Add.

How many routers can be in a subnet?

Pretty much every home router uses a subnet that supports a maximum of 250 connected devices. A subnet that allows for 250 devices is specified with the first three numbers of the four numbers in an IP Address with an X serving as a wildcard. For example, very popular subnets are 192.168. 0.

Can two ports of a router be in the same subnet?

The reason you cannot have the same subnet on two interfaces on one router is answered by your own question – the router will not know where to send the traffic 🙂 Once that is done you would then perform routing via Port-Channel interface that will hold your IP address.

How do I connect two IP addresses to my router?

Connect the “LAN” port to the “network 1” network and give it a static IP address in the “network 1” subnet. Disable any DHCP server on the router. Connect the router’s “Internet” port to the “network 2” network and give it a static IP address in the “network 2” subnet.

Are the following two IP addresses in the same subnet?

The most common subnet you will see is 255.255. 255.0. So if two addresses match in the first three sections (reading left to right), and the subnet is 255.255. 255.0 for both addresses, they are in the same subnet.

Why do routers need at least 2 IP addresses?

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 with different network part of the network addresses.

Can devices in different subnets communicate with each other?

Devices in different subnets can communicate. That is the purpose of a router. Routers route packets between different networks. Even if devices in different networks are on the same layer-2 broadcast domain, you need a router to let the devices communicate at layer-3.

Can devices with the same IP address be on different networks?

This means that, in order for devices to be on the same network, the first number of their IP addresses has to be the same for both devices. In this case, a device with the IP address of 10.47.8.4 is on the same network as the device with the IP address listed above.

How does the subnetting of an IP address work?

The answer is within something called a Subnet Mask. An IP address is always combined with a Subnet Mask, and it is the Subnet Mask that determines which part of the IP address that belongs to the IP network and which part that belongs to host addresses. Before going through the example please have a look into the subnetting of class C address.

Why do I need a router for a layer-2 broadcast domain?

Even if devices in different networks are on the same layer-2 broadcast domain, you need a router to let the devices communicate at layer-3. That is because each host will compare the destination layer-3 address and its own layer-3 address and mask to see if they are on the same network.
