Essential Nmap Commands with Examples for Network Scanning
Introduction to Nmap Commands When it comes to network scanning and security auditing, Nmap stands out as one of the most versatile tools available. Whether you are an experienced sysadmin or a beginner trying to understand your network, knowing how to use Nmap commands efficiently is crucial. In this guide, we will explore various Nmap […]
Junos
Junos kernel is basically based on FreeBSD unix os. It is an open source software. This is feature-rich network operating system which has been using in a very wide range of Juniper Devices which includes switches, routers etc. It function into multiple software processes and each process handles a device function. This functionality enhances its […]
Difference between Connection-oriented protocols vs Connectionless Protocols
If we talk about both protocols then both works for making connection between two or more devices. This service offered in Network Layer. Sending and receiving data includes connection establishment and termination. And there comes these protocols. Where we can go for connection oriented or connectionless depending on service. Connection-oriented Protocols This connection protocol ensures […]
IPv6 Address
IPv6 Internet Protocol (IP) version 6 is the basically successor of IPv4. It was developed to deal with the issue arising due to exhaustion of IP’s of IPv4. IPv6 addresses are 128 bits in length so it has a very large number of address space which is basically 2128.IPv6 introduces a new types of communication […]
What is Supernetting?
Supernetting is the opposite of Subnetting. It is the process of combining multiple subnetworks to one. This is also known as Class Inter-Domain Routing (CIDR). Once we combine multiple networks to make it a single one then we have an improved version of routing as we have a less number of routing tables. We basically […]
Subnetting
The first question is why we need Subnetting. Subnetting is very important term in Network. Let’s say we have 10 devices on which we need to assign the IP address on them. Let’s say we have a Class C IP address range and will have 254 usable IP address but we need only 10. So […]
Foundational Concepts in Networking
Collision DomainA collision domain is basically state that how many devices can send the data at same time and so it can collide to each other which leads to data less. So we always prefer to have less number of collision domains. Like in a Hub, only one device can send the data at one […]
OSI Model
It stands for Open System Interconnection. Initially there was no standard protocols but later ISO (International Standards Organization) has setup some common protocols to standardize network communication.OSI has been divided into seven layers. Physical LayerThis is the first layer in OSI model where data arrives in raw format (in bits). It is responsible for communication […]
