How IP and MAC Addresses Work


In the world of the internet, every single computing device has supposed to be own two addresses – where one is physical (media-access control – MAC) and the other is an Internet address. It is considered that both addresses identify the device globally. A web package requires two addresses to arrive at its destination. Any Internet software, such as a browser, uses a destination IP address to route data to a destination on the Internet. This address is contained in a data packet sent using an Internet software key.

If you want to send a message, you need the recipient’s address. No house has the same address, otherwise, it would be a mess. The Internet works the same way as postal services. MAC address and IP address are used to uniquely identify devices on the Internet. They are supposed to detect devices online in a special way. 

I-P Address

It is considered that IP address is itself determine as matchless pairs of digits which are supposed to recognize any device linked with the Internet. To understand where this email comes from, we need a little understanding of how the Internet works. The Internet is simply a set of separately connected networks. However, every single system is known as an Internet-Service -Provider (I.S.P), though if someone is willing to obtain facilities from I.S.P so that one can join the connection to the Internet as well as any weblink which is associated with it.

When data from the Internet needs to reach you, the ISP network identifies the destination as its unique IP address and forwards it to you. An IP address is a virtual address and changes depending on the network your device connects to or even each time you restart your computer. Many years ago, you kept the same IP address on your computer, but now IP addresses are usually assigned actively. Some websites always have the same IP address, called a static IP address.

M-A-C Address

On the other hand, the M-A-C address classifies an exclusive “network line” above the device. The MAC address is the “physical” address of the device. It is the hard drive manufacturer’s code. Twelve-digit hexagonal number, each device in the world has a unique MAC number. If you want to know, the 48-bit ID has 281.5 trillion combinations, so you don’t have to worry about duplication. We don’t usually care – it works behind the curtains.

Working of IP and MAC Addresses Collectively

All the same, with the purpose to allocate information from one network to another utilizing the TCP/IP standards – IP address is used. The MAC address is used to restore data to the correct device on the network. For instance – a person’s name is “William Steve,” though not enough distinctive in terms of an identifier. But what if we add your family tree (i.e. “Manufacturer”)? You were “William Steve, son of John, son of Harry, son …”. If someone wants to send you a package, can’t tell the post office to send it to “William Steve, son of John, son of Harry, son …” Even if already knows you well, it would offend the postman. That’s why your proper residential address is required.

But the address alone is not enough. Your router or modem has a unique IP address (home network) assigned by your I.S.P (email service). Devices connected to the router or modem (home residents) has unique MAC email addresses (personal names). The IP address receives data from your router or modem (mailbox) and then sends the router/modem to the correct device (receiver).

Where IP and MAC Addresses Not Make the Grade

Remember how your IP address shows your device’s connection to your ISP? What happens when another device connects to the host device and directs all web activity through it? For the rest of the web, the functionality of a single device seems to be the main tool. While there is nothing wrong with that, it can cause security issues. Another feature is that you can track IP addresses. You will be amazed at what only someone can do with your IP address.

When it comes to MAC email addresses, you should be aware of only one problem: Changing your device’s MAC address is incredibly easy. This goes beyond the unique goal of the identifier set by the manufacturer because anyone can “breakthrough” someone else’s MAC. Functions like MAC filtering also make it almost unnecessary. In both cases, IP and MAC email addresses are still useful and important, so there won’t be any soon.

The Mailroom Metaphor

An IP address is very similar to your email address. Anyone who knows your email address could send you an email. There may be a simple or difficult way to receive this message, but as important as it is, it doesn’t matter. The same goes for databases that travel networks like the Internet. 

It can be directly considered corporate mail. You can send the letter to the “Complaints Department, Large Companies”. The postal service sends this letter to the company. A company post office representative then announces that the letter will be sent to the complaints department and mailed to the office. All the packaging is actually on the way for you. The route then determines for which computer this package is used and directs it (this is the name of the route). The MAC address is very similar in colour, size, and physical mailbox shape. It is enough for the recipient (your internet route) to recognize it, but it is unique to you.

MAC Email Addresses and Security

For security reasons, MAC email addresses are not discussed because they never travel outside of your home network and cannot hide them because they are necessary for network operation. Many adapters allow you to override the MAC address while recognizing your computer on the LAN. In many cases, you can come from another IP address, for example, through anonymous services, etc., but this does not change the fact that the IP address is still available to your computer. 

Other software can do the same and even send data to someone else for some reason. Connecting to the Internet requires the necessary steps to ensure security. After all, there is no way to “hide” your IP address without disconnecting from the Internet. What you should do are the classic phases of network security, such as Cisco and CompTIA certification training to support your routers, update your system, run anti-malware scans, back them up regularly, and more.
