MAC and IP are the addresses that uniquely defines a device and a connection in a network. A MAC address is a number assigned to the NIC card by the manufacturer. IP address is a number assigned to the connection in a network. The basic difference between MAC address and IP address is that a MAC address uniquely identifies a device that wants to take part in a network. On the other hand, an IP address uniquely defines a connection of a network with an interface of a device. Let us study some other differences between MAC address and IP address with the help of comparison chart shown below.
Use DHCP or a manual IP address on Mac. An Internet Protocol (IP) address is a number that identifies each computer across the Internet or a network. When you connect to the Internet or an IP network, your computer needs an IP address. Your IP address can be provided in two main ways. If you want to set your Mac to always have the same IP address (also known as a static IP address), you can easily configure this to be set in the Network settings of OS X. This can be valid for both wi-fi networks and wired ethernet networks, and it can also be set under a specific network location.

Definition of Mac Address

Address that uniquely defines a hardware interface is called MAC (Media Access Control) Address. MAC address is purchased by the manufacturer, producing interface hardware and assign the MAC addresses sequentially to the interface hardware as they are produced. MAC address is burned into the ROM of Network Interface Card (NIC). NIC is an interface hardware that is used by the computer to become a part of a network.
MAC address is a 48-bit hexadecimal address. The format of a MAC address is MM:MM:MM:SS:SS:SS, where MM:MM:MM is a 3-byte address of the manufacturer. On the other hand, SS:SS:SS is a serial number of NIC card. MAC Address of each computer on a network is unique. When you change or replace the NIC card of your computer, your MAC address also gets changed. MAC address is used at the data link layer of OSI/TCP/IP model. ARP Mcculloch pro mac 55 shop manual. (Address Resolution Protocol) is a protocol used to receive MAC address of a device.
Definition of IP Address
The address provided to a connection in a network is called IP (Internet Protocol) address. IP address does not uniquely identify a device on a network but, it specifies a particular connection in a network. IP address is provided by the administrator of the network or by Internet Service Provider (ISP). IP address identifies both a network and the host on that network. IP address is used while routing as it specifically identifies a network connection. If your computer is on two networks so, it will have two IP addresses.
IPv4 address is 32-bit address whereas IPv6 is 128-bit address. Your IP address will get changed each time you connect to the network as it is dynamically allocated to your device when it participates in the network. IP address for a particular connection in a network can be retrieved by RARP (Reverse Address Resolution Protocol).
Key Differences Between MAC Address and IP Address

- The full form of MAC address is Media Acess Control whereas, the full form of IP address is Internet Protocol address.
- The IP address identifies a connection to a device in a network. On the other hand, Mac address identifies a device participating in a network.
- MAC address is 48 bits (6 bytes) hexadecimal address whereas, IP address has two versions, IPv4 a 32-bit address and IPv6 a 128-bit address.
- MAC address is assigned by the manufacturer of interface hardware. On the other hand, IP address is assigned by the network administrator or Internet Service Provider (ISP).
- ARP protocol retrieves the MAC address whereas RARP protocol retrieves IP address.
Conclusion:
MAC and IP address both are equally required when a device wants to communicate with another device in a network.

Fix No Ip Address Mac
Your IP address can be provided in two main ways:
- Automatically: Your computer is assigned an address using Dynamic Host Configuration Protocol (DHCP).
- Manually: Your ISP or network administrator gives you an IP address, and you enter it in the Network pane of System Preferences.

Follow these steps to enter your IP address or have it assigned automatically.

- On your Mac, choose Apple menu > System Preferences, then click Network.
- Select the network connection you want to use (such as Ethernet) in the list.
- Click the Configure IPv4 pop-up menu, then choose an option:
- If your address will be assigned automatically, choose Using DHCP.
- If your ISP or administrator gave you an IP address, choose Manually and enter the address in the IP Address field. Your ISP most likely gave you additional information such as the subnet mask, router, and Domain Name System (DNS) server address. Enter the subnet mask and router in the labeled fields. To enter the DNS server address, click Advanced, click DNS, then click the Add button and enter the address.

Note: Most IP addresses are IPv4 addresses, which look like a series of numbers separated by three periods, similar to this: 123.45.67.89. If you received an IP address that’s a longer series of numbers and letters, divided by seven colons (for example, fa80:0000:0000:0123:0203:93ee:ef5b:44a0), it’s a different type of IP address called IPv6. To enter an IPv6 address, in Network preferences, click Advanced. In TCP, change the Configure IPv6 pop-up menu to Manually, and enter your IPv6 address.
