In network communication, the use of Network Address Translation () allows for the translation of addresses to addresses when data is transmitted across the internet. Private IP addresses are reserved for use within a Local Area Network (), ensuring that multiple devices can connect and communicate internally without the need for public IP addresses. The , often provided by a , serves as the bridge between the LAN and the internet, allowing data to flow in and out of the network.
When devices connect to a network, they are assigned an IP address through an provided by a Dynamic Host Configuration Protocol () server. DHCP is responsible for automatically assigning IP addresses within the LAN, ensuring efficient utilization of available addresses. The not only provides IP addresses but also other network configuration information, such as the subnet mask and default gateway.
In addition to assigning IP addresses, DHCP also plays a crucial role in ensuring network security. Through an process, DHCP verifies the identity of clients seeking network access. This helps mitigate unauthorized access attempts, safeguarding the of the network and its connected devices.
