Network Address Translation (NAT) is a crucial networking technique used in routers and firewalls to manage the allocation of IP addresses in a network.Its primary purpose is to allow multiple devices within a private network to share a single public IP address for accessing resources on the internet. It’s a common networking method that allows multiple devices in… Read More »
What is OSPF? Open Shortest Path First (OSPF) is a routing protocol used in computer IP networks to determine the best path for data packets to travel from one router to another.It is part of the Interior Gateway Protocol (IGP) family and is widely used in large and complex networks. OSPF is designed to allow routers within an… Read More »
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 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 »
