Advantages and Disadvantages of Checking a Mac Address
Mac address is a unique identification code assigned to every device connected to a network. It helps in tracking the device location, internet usage, and other preferences. Checking of a mac address is an important feature, but it also comes with various advantages and disadvantages, which we will discuss in this article.
- Security: Mac address filtering helps in securing the network by allowing only authorized devices to connect.
- Network Management: With the help of mac address, IT admins can easily manage the network by monitoring the devices and their usage.
- Parental Control: Mac address can be used for parental control. Parents can block or restrict their children’s device from accessing certain websites or apps.
- Location Tracking: Mac address can help in tracking the device location, which is useful for businesses and organizations.
- Prevents Misuse: Mac address can prevent misuse of the internet by blocking websites that may harm the network or the device.
- Limit Bandwidth: Mac address can be used to limit bandwidth usage by setting data usage limits for specific devices.
- Easy Troubleshooting: Mac address can be used for easy troubleshooting of network issues or device connectivity issues.
- Promotes Accountability: Mac address tracking promotes accountability in an organization, which in turn promotes healthy work ethics.
- Prevents Hacking: Mac address filtering can prevent hacking attempts on the network by unauthorized devices.
- Legal Compliance: Tracking mac address can help companies comply with legal policies related to internet usage, data security, and privacy.
- No Full Proof Security: Mac address filtering cannot provide full-proof security as it is possible to spoof a mac address and gain unauthorized access to the network.
- Compatibility Issues: Some older devices may not be compatible with mac address filtering, which can be a disadvantage for those who rely heavily on such devices.
- Additional Workload: Implementing mac address filtering requires additional workloads for small businesses or individuals, which can be time-consuming.
