What Is MAC Address?

MAC Address stands for Media Access Control Address and it is a computer networking term that represents a device’s unique hardware identifying number. With a large number of devices that work on the internet to distinguish each of them there are some unique number sequences allotted to each of them. Network cards when manufactured are given these MAC addresses by manufacturers and it remains the same for that device. WiFi and Ethernet cards have MAC addresses given from the manufacturer so they can work on any network. MAC addresses need to be unique as they are identification numbers for that hardware and IP Addresses are assigned to then with this MAC address. 

The structure of the MAC address is readable to humans and consists of six pairs of characters such as numbers and letters. These pairs have colons in between them to make a proper MAC address. This address is quite easy to understand but has no use to humans as the networks can automatically recognize it. The format of the MAC address may look like this for a device or network card 0d:00:83:b1:d0:8e.

What Is DNS?

In networking, DNS means Domain Name System and this is the very thing responsible for the interaction of user with web pages without using IP addresses. For using internet users use domain names to access the websites whereas the web browsers use the IP addresses to access the same thing. DNS serves the purpose of translator between a domain name and IP Address so the browser gets the IP address every time someone inputs a Domain name.

On the internet, there are too many devices to count that are connected to each other and each of these has their IP address. These IP Addresses are used by devices to recognize other devices and DNS allows user to interact with these devices without using their IP address. It’s too much trouble to remember the IP Address be it the IPv4 or the newer and more complex IPv6 so DNS saves the trouble for users.

Each time a search is made DNS acts as a translator on the internet to make the search possible without the use of the actual IP address directly.

Difference Between Static and Dynamic IP

An IP address stands for Internet Protocol and now there are these two types of IP addresses that can be easily differentiated. There is Static IP which as it sounds is un-editable and more directed towards its permanent existence. On the other hand, Dynamic IP is dynamic as it can be changed and is editable to a better extent. There are some easy to understand the differences between both the IP and one is how it is provided. A static IP address is given to the computer by ISP whereas the dynamic IP address is mostly given by DHCP. Static IP remains the same once it is assigned to a computer of the device whereas Dynamic IP can be changed at any time.

Static and Dynamic IP is different for security reasons as well due to the less security on Static IP whereas Dynamic IP is more secure and contains less risk. The static IP address allows a device to be traceable on the other hand Dynamic IP address makes the device intractable. Stability also makes a difference in both the IPs as the Static IP address is stable as compared to Dynamic IP address.

What Is an IP Address?

IP Address stands for Internet Protocol Address and is a numerical name that each of the devices working on the internet is assigned. For numerous computers and devices communicating on the internet, there is the same number of IP addresses. This IP address is made up of numbers that can be read by users normally as a simple language. It serves a major role in computer networking and has two functions in networking. The two functions of the IP Addresses are interface identification and location addressing as it is responsible for the identification of devices or computers. 

The two Internet protocols that are quite well-known are Internet Protocol version 4 (IPv4) and Internet Protocol version 6 (IPv6). IPv4 is an older or outdated version as it reads IP addresses as a 32-bit number. IPv6 was next to IPv4 as the users across the internet increased and IPv4 ended with the lack of IPv4 addresses. IPv6 turned out better due to the 128-bit number in IP addresses that started in the year 1998. IP addresses are simple numbers and so they are readable without need of any software as it’s just a simple numerical format.
