Question: What Address Is Used For Ethernet Broadcasts?

What is the broadcast address of a network and what is it used for?

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.

It is important for remote announcements in network segment..

Is broadcast address the same as default gateway?

A broadcast address is the one that is used by one host to communicated to another host on the same network whereas the default gateway is this address that is used by all hosts to communicate with hosts outside the network/subnet. Traffic destined to other computers on another network is routed through the gateway.

What is direct broadcast address?

Can two devices have same MAC address?

MAC Addresses are ‘burned’ into the Network Interface Card (NIC) and cannot be changed. … No other device on that local network subnet can use that MAC Address. If two devices have the same MAC Address (which occurs more often than network administrators would like), neither computer can communicate properly.

What is 255.255 255.255 used for?

255.255. 255.255 is a special broadcast address, which means “this network”: it lets you send a broadcast packet to the network you’re connected to, without actually caring about its address; in this, is similar to 127.0. 0.1, which is a virtual address meaning “local host”.

What is the broadcast address for Ethernet?
