Packet Tracer is a cross-platform visual simulation tool that allows users to create and configure network topologies and devices. It is mainly used for educational purposes by Cisco Networking Academy students and supports various protocols and features.
Network address translation (NAT) is a method of mapping an IP address space into another by modifying network address information in the IP header of packets. Learn about the history, types, methods and applications of NAT, and how it relates to IPv4 address exhaustion.
A default gateway is the node in a network that forwards packets to other networks when no other route matches the destination IP address. Learn how default gateways work, how to configure them, and see examples of single and multi-router networks.
EIGRP is a Cisco proprietary routing protocol that uses five metrics to calculate the best path to a destination: bandwidth, load, delay, reliability and MTU. EIGRP is a hybrid protocol that sends only incremental updates and supports load balancing, authentication and different PDMs.
Learn about the origins and development of the Internet, the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate. The article covers the early research, the protocol wars, the commercialization, and the impact of the Internet on various aspects of life.
Tunneling protocol is a communication protocol that allows data to move from one network to another through encapsulation. Learn how tunneling works, what are its uses and common protocols, and how to bypass firewalls with tunneling.
ARP is a protocol for discovering the link layer address of a host with a given IP address. The destination address in an ARP request frame is the IP address of the target host, while the source address is the IP address of the sender host.
A gateway address is a router interface that sends packets out of the local network. It has a logical address (gateway IP) and a physical address (MAC address). Learn how to configure and use gateway address.
