Addressing, packets and protocols
MAC AND IP
The "192.162" identifies the network. "1" can show the port but this often changes on the use of a router. "05" is your personal code, this could change every time you log in.
The MAC address is a unique value associated with a network adapter. MAC addresses are also known as hardware addresses or physical addresses. They uniquely identify an adapter on a LAN.
MAC addresses are 12-digit hexadecimal numbers (48 bits in length). AC addresses are most often assigned by the manufacturer of a network interface card (NIC) and are stored in its hardware, such as the card's read-only memory or some other firmware mechanism.
