Is it possible to communicate between two networks without a router?

Is it possible to communicate between two networks without a router?

with routing protocols — a method for routers to communicate their reachability. But in your scenario routing protocols are not required to ensure communication between two networks because two networks are directly connected networks for router . That’s why routing protocols are not required on router .

Can two different networks communicate?

On a computer network, all devices that are connected to the same local network can talk directly with each other. But to do so they need to have IP addresses that belong to the same IP network. Computers that belong to different IP networks have to communicate with each other via a router.

Is a router necessary to connect subnets?

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.

How two devices can communicate?

Using the Internet, computers connect and communicate with one another, primarily using the TCP/IP (Transmission Control Protocol / Internet Protocol). Think of TCP/IP as a book of rules, a step-by-step guide that each computer uses to know how to talk to another computer.

Which network connectivity device is best suited for communicating between two similar networks that uses two different protocols?

Gateways
A gateway is a network node used in telecommunications that connects two networks with different transmission protocols together. Gateways serve as an entry and exit point for a network as all data must pass through or communicate with the gateway prior to being routed.

How does the two systems communicate in an Ethernet network?

The Ethernet cable is a common medium for every computer in the network. Switch can be used to split the wired network. Multiple cables are connected to the switch which is responsible for data transmission.

How can I tell if two networks are connected to the same network?

You need to know the subnet mask. The subnet mask tells you which bits of the address represent the subnet, and which bits represent the host within the subnet. If your subnet is a /24 (255.255. 255.0), then any address whose first three octets match would be in the same subnet.

Does an Ethernet switch have an IP address?

Final Thoughts. To summarize, unmanaged and layer 2 switches do not have an IP address, whereas managed and layer 3 switches do. Having an IP address assigned to your switch provides you with a way of connecting to it remotely and perform any configuration that is needed.

Does switch understand IP address?

Ethernet Switch operates at Layer 2 (Data Link Layer) Contrary to routers, Ethernet switches don’t understand IP packets but frames. As an IP packet has info for router, a frame has info for switch.

Can two computers on the same network communicate with each other?

Two PCs on a different network will not communicate with each other unless they are assisted by a router. However, if they are directly connected to each other, or connected to a common switch, they will ping each other using the above process, where each network interface has its own IP address configured as the gateway address too.

How to connect to another network?

To reach other network a router is required. This router should have at least one interface within that local network, where it will receive the data meant for other networks to further process it. Original question was posted by “Network Specialist” in the thread

Can two hosts be connected to two switches in different subnets?

If two hosts connected to 2 switches in different subnets, intervlan communication will not occur, 03-12-2018 02:52 AM 03-12-2018 02:52 AM If you ask this question as straightforward then my answer is no. But some articles as showing that it is possible but not tested in my lab.

Why can’t two PCs connect to each other via NAT?

Under normal, non-hacker circumstances, the NAT routers at each end would need to have port forwarding enabled for each PC’s private address, or the routers would need to be using one-to-one NAT, to enable the two PCs to communicate via the public addresses. You could also use a VPN between the two PCs to get around the NAT problem.
