What Is The Difference Between An Ip Address And Mac Address?
One of the most asked questions in the IT world is - what is the difference between MAC address and IP address? While people are not always knowledgeable in these matters, it is a topic that deserves a lot of explanation. After all, security is paramount for any company, regardless of what industry they belong to. Any hacker with the means to connect to your network can use that network for his own gain.

As far as networks themselves are concerned, they operate using IP addresses. These are unique to each network, but the idea behind them is to make it as easy as possible for people on the network to identify themselves. This makes it simpler for users to establish communication with each other. The network operators can also assign IP addresses to different computers on the network. This allows them to create virtual LANs or Virtual Private Networks.
There are many advantages of having IP addresses rather than MAC addresses. For one thing, an IP address is a globally recognized code that can be used to identify computers on the internet. Secondly, when a packet of data is sent from one computer to another, it will be identified by the network's IP address. Thus, when you are surfing the internet you will know that the site you are visiting is the one you are supposed to be at.
What is the Difference Between an IP Address and MAC Address?
On the other hand, MAC addresses are a series of numbers that are used for internal networking within the computer. Each computer has its own MAC address. This helps to prevent hacking or tampering when using systems that have both IP addresses and MAC addresses. However, there is a difference between the two in that while an IP address can be traced back to a particular computer, a MAC address cannot.

So what does this mean? If your computer were to send you a packet of data which came from someplace else, such as a router or a wireless hotspot, it would not be possible to tell which computer had sent the packet. To solve this problem, an IP address is used. Each computer has its own IP address, which can be traced back to a specific location on the network. Hence, the packets of data sent out from a particular computer are able to be matched with the IP address of the source machine.

It goes without saying that every machine has an IP address. But when a packet of data is sent out from a different machine on the network, then it becomes necessary for the network administrator to have a MAC address. The MAC address is not used to match the source MAC address of the packet of data but rather it acts as a check point by which the source IP address and the MAC address can be matched up. Hence, there are times when you will receive a packet of data from somewhere but the MAC address of the machine that sent the packet is different from the one you have on your system.

One way of knowing whether the MAC address being used is the same as the IP address is to check for the MAC address during a login process. If your MAC address is different, then you should ask for logon help. You will probably get a message saying that you do not have a matching MAC address. This could be because your system uses a different type of software to logon to the Internet as compared to the one used in some of the Windows operating systems. If you are trying to access a site that uses a different browser than your system, then your MAC address will be blocked. Hence, it is probably a case of your system having an IP address and not a MAC address.
There are a number of technical reasons for why the two addresses may be different. A software incompatibility may be the reason behind the IP difference. Another reason for the IP difference may be that the IP address is static while the MAC address is dynamic. If your computer is configured such that it will remember the IP address and only update the MAC when it needs to, then it may be using an IP address that is static. In such cases, if you have been using a shared network with a site that is using a dynamic IP address, then you may have found the difference between the two addresses to be quite obvious.
