Network Address Translation

What is Network Address Translation (NAT)? Network address translation (NAT) is a mechanism that allows several devices on a local network to share a single public IP address while maintaining their own distinct private IP addresses. This is made possible by NAT, which translates network devices' private IP addresses to their public IP addresses so they can […]

If a business or organization wants its employees to be able to freely exchange information and resources, as well as maintain open lines of communication, they need a sophisticated network architecture. A network engineer is required to handle the network architecture. By reading this article, you will know the answer to the question, "what does […]

OSPF Metric Calculation and EIGRP Metric Calculation

Best Path Calculation Methods - OSPF and EIGRP Metric Calculation

OSPF metric calculation is used to find the shortest path by using cost as a metric and determining the cost of paths to know the best path to the destination. Before understanding the OSPF and EIGRP Metric calculation, you need to know that: The automatic and dynamic exchange of routing information between routers is made […]

15 OSINT (Open-source Intelligence) Tools for Penetration Testing

We live in a digital world where everything is online, and that's where you have to find relevant information about everything. This information can be easily gathered using OSINT tools as the internet world is vast, but it is impossible to find the information you are looking for every time. Does that mean that the […]

AAA in networking stands for Authentication, Authorization, and Accounting. It is a set of services that provides more security for accessing network resources. AAA is a requirement, when it comes to network security. In this blog, we will take a look at what is AAA in networking, its commands, protocol, and components. So, without any […]

What is Access Control List (ACL) in networking?

You may have heard about the Access Control List or ACL. It is used to control permissions to a computer system or network, but do you know what is Access control list? As we know, the Internet is a network of networks, and routers play a vital role in having connectivity between different networks. Routers […]

Introduction to VLAN, Its types, Range and Advantages.

In networking, as we know, switches are used to create networks, while routers are used to connect different networks. By default, switches forward both broadcast and multicast out of every port but not the originating one. However, if you require to divide a single broadcast domain into smaller ones with security in some networks, then […]

Everything you need to know about FHRP (First Hop Redundancy Protocol)

Before learning about FHRP (First Hop Redundancy Protocol), a network engineer must understand why redundancy is even required in networking. Why Redundancy? Redundancy plays a vital role in networking. Network redundancy assures business continuity by avoiding failure of the network. By keeping operations running all the time, it boosts productivity. To have a dependable network, […]

QoS in Networking

Enterprise networks must offer dependable and quantifiable services to enable the transmission of delay-sensitive data, voice, and video. So, QoS is employed by enterprises to fulfil the traffic demands of sensitive applications, such as real-time voice and video, and to stop the quality from degrading as a result of packet loss, delay, and jitter.

Introduction to Network Protocols

Network Protocols are the set of rules for communication between network devices, including the ways devices can identify and make connections with each other.

Your Complete Guide to Routing Information Protocol (RIP)

In 1981, the Routing Information Protocol (RIP) was first developed as GWINFO in the Xerox Network Systems (XNS) protocol suite for the Xerox PARC Universal Protocol. RIP, which was first described in RFC 1058 in 1988, has a reputation for being simple to set up and use on small networks.
