MAC address is assigned by the manufacturer of the network interface card. It is stored in the hardware. It is also known by the name physical address, Ethernet hardware address, adapter address and hardware address. As it is mostly assigned by the manufacturer, it encodes manufacturer’s registered identification number. It is inbuilt in firmware mechanism or card’s Read Only Memory.
It is used for communication purposes on physical network segments. These are of great use in Media Access Control protocol sub layer found in OSI reference model. Though it is globally accepted unique identification permanent number but with MAC spoofing process it can be changed on hardware. This spoofing is within local broadcast domain only.
MAC address spoofing is different from IP address spoofing because in it the response is received by the spoofing party. In IPv4 world, limit of MAC address is within local network only. In such cases MAC address of any computer which is positioned behind the router is well within the router. So your computer can not be detected on the internet but can be identified on local computers.
In IPv6 world, MAC address is visible to connected server, thus making it available to internet connected computers. In IPv6 every PC, printer, server or net work device is assigned a routable address. ISP can recognize your identity, your files etc unless the communication between your computer and ISP is encrypted by use of a VPN.
Benefits of Hiding MAC Address
In general most of the computer users have tendency to sniff other users’ Wi-Fi traffic to use for their benefits. They note down the addresses of connected computers. Now they use your MAC allowed address by changing their own and easily connect to your network. This practice can be prevented to provide you benefits by hiding MAC address in your business or secrecy, by use of suitable software meant for the purpose.
Recommend a software hide MAC Address
If your opponent in business knows your MAC address, with right tool he or she can follow your data on internet. Your address is available over Wi-Fi networks in spite of secured WPA or WEP Encryption. So to prevent access to your system, hide MAC address. Use of software for the purpose is strongly recommended because such simple program provides effective control and security to systems.
The software like Change MAC Address is with straight forward interface. The interface displays true Media Access Control address of the computer on which it is loaded. It also displays network adapter. The software is quick to deliver with just a click on ‘Hide Button’. You get a new MAC address with this action. In the advanced mode of software, one can easily create MAC address for quick and accurate results.
Some networks allow filtering of MAC addresses to prevent unwanted access. But it is not a sure method to prevent the hacking. So always use a software like Change MAC Address for privacy.
