What is the purpose of the network address?
Computers on a network use a network address to identify, locate and address other computers. Besides individual devices, a network address is typically unique for each interface; for example, a computer’s Wi-Fi and local area network (LAN) card has separate network addresses.
What device uses IP addresses?
Every device that connects to your internet network has a private IP address. This includes computers, smartphones, and tablets but also any Bluetooth-enabled devices like speakers, printers, or smart TVs. With the growing internet of things, the number of private IP addresses you have at home is probably growing.
Can we use network address?
This being said, you still should not assign a network address to any specific host in a network: Network address is essential for routing. This concept is used extensively in RFCs (RFC 1812).
Why do devices need network addresses?
Devices in a network require addresses so that they can be able to be identified uniquely. For communication to take place in a network, the devices must be able to recognize each other. This is the reason that these devices are assigned addresses.
What is the purpose of network address and broadcast address?
255.0, because of simplicity of calculations of network address – last octet is zero, and first three octets are representing network address. Broadcast address is the last address in the network, and it is used for addressing all the nodes in the network at the same time.
Why is 192.168 always used?
The reason 192.168 exists is so that you do not need to ask someone else for an address. You can pick ones that start with 192.168 and there will be not conflict with any one else because those addresses may only used in your network(s) and are not used by some outside your network to reference your machines.
How do you block someone from your WIFI?
Go to More Functions > Wi-Fi Settings > Wi-Fi Access Control, and toggle on Wi-Fi Access Control. Set the router to Blacklist (block access from devices in the list) or Whitelist (allow access from only devices in the list) according to your needs.
Why is network addressing important in computer networks?
Network Addressing is one of the major responsibilities of the network layer. Network addresses are always logical, i.e., software-based addresses. Each interface is capable of sending and receiving the IP packets, so IP requires each interface to have an address.
Why addressing is needed in data communication?
IP addressing provides mechanism to differentiate between hosts and network. The host which needs to communicate outside its subnet, needs to know destination network address, where the packet/data is to be sent. Hosts in different subnet need a mechanism to locate each other.
