In a local area network (LAN), routers has the knowledge of the routes to host devices within the network. However, in a wide area network (WAN), which typically consist of two or more routers, routers in the network does not know routes to host devices or network addresses beyond those directly connected to its interfaces. […]

Address Resolution Protocol (ARP) and Dynamic Host Configuration Protocol (DHCP) are two protocols used in associating IP addresses to host devices in a network. ARP is a protocol that is used to map an IP address to a physical machine (mac address) by sending a multicast message on a LAN and recording the mac address

Internet Control Message Protocol (ICMP) and User Datagram Protocol (UDP) are two communication protocols employed for the delivery of data in a network. ICMP operates at the network layer of the TCP/IP suite, assessing network performance and reporting errors in network traffic. It is commonly utilized with the ping and traceroute commands. The ping command

Hot Standby Routing Protocol (HSRP) is a Cisco proprietary First Hop Redundancy Protocol designed to enhance network reliability by enabling multiple routers to collectively serve as the default gateway for host devices within a subnet. The primary goal of HSRP is to establish redundant connections to the internet for a subnetwork, thereby ensuring a highly

Transport control protocol (TCP) and internet control message protocol (ICMP) are two communication protocols used for the transport of data between sender and receiver in a network. These two protocols work behind the scenes to ensure your online experience is seamless. In this post, we will walk you through the differences between TCP and ICMP,

Dynamic Host Configuration Protocol (DHCP) is a protocol that automatically assigns IP addresses to host devices existing on a network from the pool of IP addresses configured on the DHCP server. In small networks, the DHCP server is always in the same subnet with all the DHCP clients; however, when the network grows to two

Dynamic Host Configuration Protocol (DHCP) is a protocol that dynamically assigns IP addresses to any host devices in a network from a pool of IP addresses configured on the DHCP server. Although DHCP is traditionally configured on a router or on a dedicated server, a Layer 3 switch can also serve as a DHCP server.

Network Address Translation (NAT) comprises three main types, with static NAT and dynamic NAT being two of them. Static NAT is a form of address translation that establishes a permanent one-to-one mapping between an inside local IP address (private IP address) and an inside global IP address (public IP address). This mapping enables the private
Dynamic NAT vs. Static NAT: Comparison and Differences Read More »
This article will guide you on how to Configure Dynamic NAT on Cisco Router using Packet Tracer. Network Address Translation (NAT) is a crucial algorithm utilized to map private IP addresses to public IP addresses, enabling routing over the internet. Due to the substantial increase in the number of internet users over the past few

In this article, we will explore the process of setting up static NAT on a Cisco router. Network Address Translation (NAT) is a algorithm that maps private IP addresses with public IP addresses, facilitating internet routing. There are two primary types of IP addresses: IPV6 and IPV4. Initially, IPV4 served as the primary IP addressing
