How many digits are in a network mac address
Address Provider: The IP address is provided by the administrator of the network, DHCP(Dynamic Host Configuration Protocol), or the ISP(Internet Service Provider).Address Type: The IP address is a software-based or logical address, while the MAC address is a hardware-based, burnt-in, or physical address.Purpose: IP address is mainly used to identify the connection of a node on the network, while the MAC address is used to identify the unique address of that node.Following are the dissimilarities between the MAC and IP address: The MAC address works on the Data-Link Layer of the OSI or TCP/IP reference models. The first 24 bits represent the OUI(Organization Unique Identifier), and the next 24 bits represent the vendor's specific information.
The 48 bits MAC address has two parts of 24 bits each. These hexadecimal digits can be separated either by hyphens(-) or colons(:). MAC is a 48 bits address which either contains 6 groups of 2 hexadecimal digits, or 3 groups of 4 hexadecimal devices. It is embedded into the hardware and remains constant for that device. The MAC address is provided by the manufacturer of the NIC(Network Interface Card).

It is also called the physical address, or the Burnt-In address, or the software address. MAC address is the address that uniquely identifies a node on the network. MAC Address(Media Access Control Address) The IPv6 addressing can not be used for broadcasting. It supports a packet size of up to 1280 bytes. The optional fields are not also available in IPv6 addressing.
The IPsec support(for security feature) is mandatory in IPv6. The header field of the IPv6 is 40 bytes, but the checksum bits are not present in the header file. This address is available in hexadecimal form along with semi-colons(:) in between. IPv6(Internet Protocol Version 6): IPv6 is a 128-bits address.The IPv4 addressing can be used for Multicasting and Broadcasting the data packets. It supports a packet size of up to 576 bytes. The optional fields are also available in the IPv4 addressing. The IPsec support(for security feature) is optional in IPv4. The header field of the IPv4 is 20 bytes, and the checksum bits are present in the header for error control. This address is available in decimal form along with dots(.) in between. IPv4(Internet Protocol Version 4): IPv4 is a 32-bits address.There are mainly two types of IP addresses: It is used in the network layer of the OSI or TCP/IP reference models. It is mainly used in routing operation as it specifically identifies a network connection. IP addresses are available in binary form. It may be temporary and keep on changing each time whenever a device connects to different networks. IP addresses are generally provided by the administrator of the network or the Internet Service Providers(ISP). It is termed as the 'Logical Address' which is provided to a connection in a network. IP Address(Internet Protocol Address)Īn IP address is an address that uniquely identifies a network connection. We'll also learn the dissimilarities between them.
We'll learn about these two addresses in detail. If we correlate this example in networking, then the IP address will be the address of the network connection in which multiple devices can be present, and the MAC address will be the address of specific nodes, where we want to deliver the data. The two things are - Receiver's address(it may contain house number, street, city, state, and pin code), and the receiver's name(in order to specifically identify the right person to deliver the courier). The sender has to specify two things about the receiver in order to successfully send the courier. So, before defining them, let us first take an example to explain them.įor Example, if someone has to send a courier to some other person. Now, again there is a confusion between these two. This can be possible only with the help of the MAC and IP addresses. But a question always arises in our mind that how one device will uniquely identify the other device in the network. In computer networks, all the network devices can connect and communicate with each other.
