Each computer on a local network has its own network address and network name. This identification of machines is one of the foundations on which the functioning of networks is based. Using Windows tools and third-party programs, you can determine the hostname by IP.
It is necessary
- - a computer with Windows OS;
- - network connection;
- - installed support for the required protocols.
Instructions
Step 1
The ping command is used to obtain information about the state of the network. It determines the health of the network and the time spent on transferring packets along the client-server and server-client routes. When using the –a parameter, new versions of the command determine the computer name by IP.
Step 2
From the Start menu, select Run and type cmd into the search bar. In the command window, type ping –a 10.0.0.20, where 10.0.0.20 is the conditional IP of the remote computer on the local network. The system will display information about the node, including its name.
Step 3
If your version of ping does not support this feature, use nbtstat with the -a option. This command returns the NetBIOS name table of the remote host. A prerequisite is that the computer supports the NetBIOS protocol. Call the command line with cmd and enter nbtstat –a 10.0.0.20.
Step 4
The name of a computer on the local network can be determined using the NSLookup command if the TCP / IP protocol is installed on it and at least one DNS server is specified in the protocol parameters. The team diagnoses the operation of the DNS and displays information about its infrastructure.
Step 5
At the command prompt, type NSLookup 10.0.0.20. The command returns the name and IP of the server on this network, the name and IP of the remote computer. A reverse lookup is possible: if you enter a computer name, the command will display its IP address.
Step 6
You can use the tracert command. It monitors the route of data packets in TCP / IP networks and, therefore, will only work on the computer on which this protocol is installed. At the command prompt, enter tracert 10.0.0.20. The destination will be the name of the remote host. On unix-like networks, the traceroute command is used for this purpose.
Step 7
To determine the parameters of the local network, special scanners are used. Depending on the complexity, they collect information about the hosts on the network, analyze traffic and test its operation. However, if your computer is on an office network, the administrator is unlikely to approve of actions to collect such information.
