Zenmap topology1/2/2023 ![]() This IP address separation is based on the subnet mask. Each IP address identifies a network and a workstation (host). IP addresses can be IPv4, having a length of 4 bytes or IPv6, with a length of 16 bytes.Īn IPv address can be: 192.168.100.1. The data is encapsulated in IP packets, with a header containing information about the source address, destination, package size, etc.įor an Ethernet interface, MTU (Maximum Transmission Unit) is normally 1500 bytes. The Internet protocol is the protocol through which data flows from one computer to another via the Internet, based on IP addresses. This network card has a MAC address (which is unique), consisting of 6 bytes, based on which a PC will be identified in the network. Interconnection between networks is done with routers, which in the OSI model are Layer 3 (for data traffic targeting use IP addresses).įor networking, any device has a network interface card (Ethernet, FO, Wi-Fi), NIC. In the OSI model, the switches are Layer 2 (for data traffic targeting, they use MAC addresses rather than IPs). In general, an IT network is comprised of computers, interconnected by switches. Wide Area Network - across the entire earth globeĬommunication in a computer network is based on the OSI reference model and more recently based on the TCP / IP model. Metropolitan Area Network - at a city level Local Area Network (LAN) - small networks If you have any need to map a network or analyze your network topography, Zenmap is the way to go.Next > Introduction IT networks are composed of computers interconnected to exchange information. Zenmap makes easy work out of the complicated Nmap command utility. Fortunately, between the other tabs, you can get all of the information you need quickly and easily. When not in real time this output can really be a pain to get through. While the scan is running the output is displayed in real time so it's easy to read. The only downfall of this is the Nmap Output is a bit cramped together. Once you have a scan completed you can save your scan and open it for later viewing. ![]() As your scan is running this is the only tab you can view - and it will give you every piece of information you need.Ī nice feature of Zenmap is the ability to save scans. To get the low-level details of your scan take a look at the Nmap Output tab. Obviously the Scan Details tab is where you will get a good summation of your scan. There are five tabs that will give you various information about the scan. However, if you opted to go the Profile route you will need to select your new profile from the Profile dropdown list.Īfter your scan has completed you can take a look at your scan results. Once you have finished configuring your scan via the Wizard you can hit the Scan button.
