The (v4]]) and () are two fundamental protocols that enable communication within computer networks. These protocols are responsible for assigning unique IP addresses to devices connected to the network. An IP address is a numerical label assigned to each device, allowing them to communicate and exchange data.
In addition to IP addresses, devices also have a unique identifier known as a (). are associated with the physical of a device and reside at the of the . Unlike IP addresses, MAC addresses are assigned by the manufacturer and are permanent, making them unique to each network interface.
When it comes to IP addresses, there are two types: and . Public IP addresses are unique across the entire internet, allowing devices to communicate with other devices on the internet. On the other hand, private IP addresses are used within local networks to enable communication among devices within the network. Private IP addresses cannot be directly accessed from the internet, and Network Address Translation () is often used to translate private IP addresses into public IP addresses.
However, it's important to note that MAC addresses are not exposed to the internet, making them less vulnerable to attacks like . This security measure prevents unauthorized individuals from impersonating devices by spoofing their MAC addresses. By manipulating MAC addresses, attackers can gain access to networks, intercept data, or launch various malicious activities. Therefore, it is crucial for network administrators to implement proper security measures to protect against mac address spoofing and ensure the integrity of their networks.
