IP communication protocol runs in the third layer of the mark (the network layer), regardless of the media kind of the cardinal layer. It trasowalny (routable), and as follows allows the routing which takes place is the third layer. To ensure the success of the communication in this manners is top-priority to name IP addresses of network interfaces devices. | |

The beforehand 24 bits are the network anniversary card fabricator, the remaining 24 bits are a one of a kind identifier of a carbon copy of the card. As a replacement for example, oration 00:0 A: E6: 3E: FD: E1 indicates that the liable act was produced via Elitegroup Computer Practice Co.. (ECS) and the farmer gave her count 3E: FD: E1. Sometimes you can upon with an warning that the MAC deliver is a 6-byte. Since 1 byte is 8 bits, so 6 bytes corresponds to 48 bits. The original 3 bytes (vendor jus civile 'civil law') means the fabricator, the other 3 bytes depict oneself another (in perfect accord) a duplication of the card. Newer Ethernet cards earmark you to change the MAC speech assumption to them. | ||
