open terminal performs: the ifconfig -a command can, as shown in FIG white background information that is.
enp0s3 represents the first NIC, which HWaddr represent the physical address of the network card, you can see the current physical address of the network card (MAC address) is 08: 00: 27: 4E: E0: ae
inet addr IP address of the network card used to represent, IP address of this card is 10.0.2.15, broadcast address, Bcast: 10.0.2.255, mask address mask: 255.255.255.0
LO is a bad return address of the host, which generally is used to test a web application, but do not want user LAN or outside the network to view, and the view can only run on which network interfaces on this host. For example, to specify HTTPD server back to the bad address, will be able to see what you stand WEB site in browser and enter 127.0.0.1. But only you can see, the host or other LAN users do not know.
First line: connection type: Ethernet (Ethernet) HWaddr (mac address hardware)
the second row: the IP address, subnet mask card
Third row: the UP (NIC on state on behalf of) the RUNNING (NIC cable is representative of connected to) the mULTICAST (supports multicast) the MTU: 1500 (maximum transmission unit): 1500 bytes
fourth, the five elements: receive and send data packets statistics
