Editor to share with you what is the difference between mac address and ip address. I hope you will get something after reading this article. Let's discuss it together.

Differences: 1. The length of the MAC address is 48 bits (6 bytes), while the IP address is 32 bits. 2. The MAC address is applied in the second layer of OSI, namely the data link layer, and the IP address is applied in the third layer of OSI, that is, the network layer. 3. The allocation of MAC address is based on the manufacturer, and the allocation of IP address is based on the network topology.

The difference between MAC address and IP address

First, the difference of address length

1. The length of the MAC address is 48 bits (6 bytes), usually expressed as 12 hexadecimal digits, separated by colons every 2 hexadecimal digits, for example, 00:50:29:5A:8H:1E is a MAC address.

2. The IP address is 32 bits, which is composed of four 8-octets separated by dots. For example, 192.168.0.1 is an IP address, which is called dotted decimal format.

Second, the difference on the addressing protocol layer

1. The MAC address is applied in the second layer of OSI, namely the data link layer. Data link layer protocols allow data to be transferred from one node to another on the same link (via MAC addresses).

2. The IP address is applied to the third layer of OSI, namely the network layer. The network layer protocol enables data to be transferred from one network to another (ARP finds the MAC address of the intermediate node according to the destination IP address, transmits it through the intermediate node, and finally reaches the destination network).

Third, the basis of distribution is different.

1. The allocation of MAC addresses is based on the manufacturer.

The MAC address is written inside the hardware when it is produced by the network equipment manufacturer. This address has nothing to do with the network, that is, no matter where the hardware with this address (such as hub, network card, router, etc.) is connected to the network, it has the same MAC address and is immutable.

2. The allocation of IP addresses is based on network topology.

The IP address consists of two parts: the network address and the host address, and the number of bits assigned to these two parts varies with the address class (Class A, Class B, Class C, etc.).
