What Is DHCP Snooping? The Dynamic Host Configuration Protocol (DHCP) allocates IP addresses dynamically, it leases addresses to connected devices and the addresses can be reused when no longer needed. All connected Hosts and end devices that require IP addresses obtained through DHCP must communicate with a DHCP server across the LAN. DHCP snooping acts like a firewall… Read More »
What is VLAN? A Virtual Local Area Network (VLAN) is a network technology used to divide a single physical network into multiple logical networks. This division is achieved at the data link layer (Layer 2) of the OSI model. VLANs are widely used in enterprise networks for their ability to improve network efficiency, security, and manageability. Key Concepts… Read More »
What Is Dynamic Host Configuration Protocol – DHCP? Dynamic Host Configuration Protocol works in a client/server mode. DHCP enables clients on an IP network to obtain or lease IP addresses or configurations from a DHCP server. This reduces workload when managing a large network. DHCP protocol is described in the RFC 2131. Most modern operating system includes DHCP in… Read More »
The DHCP server’s most fundamental task is Providing IP addresses to clients. DHCP uses three different address allocation mechanisms when assigning IP addresses: Manual Allocation: The administrator manually assigns a pre-allocated IP address to the client and DHCP only communicates the IP address to the device. Automatic Allocation: DHCP automatically assigns a static IP address permanently to a device, selecting it from… Read More »
What is Frame Relay Address Mapping? Frame Relay is a widely used packet-switching technology in the field of telecommunications and computer networking. It allows data to be transmitted in discrete units known as frames over a wide area network (WAN). These frames are used to encapsulate data before transmission and are then sent to the destination across the… Read More »
