Windows get host by ip — Ваш верный помощник с OS Windows

A reverse name resolution zone file is used to translate an IP address in a particular namespace into a fully qualified domain name (FQDN).

If this file has been configured on a name server, it becomes possible to find a hostname from an IP address.

This note shows how to get a hostname from an IP address from the command line in Windows, Linux or MacOS using the nslookup command.

Cool Tip: How to setup a reverse name resolution! Read more →

Execute the nslookup command as follows from a terminal in Linux/MacOS or from a command prompt (CMD or PowerShell) in Windows to find the hostname by IP:

$ nslookup 192.168.0.15
- sample output -
Server:  router.net.infra
Address: 192.168.0.1

Name:    my-box-hostname.net.infra
Address: 192.168.0.15

The command above performs the reverse lookup and converts the IP address to hostname by querying the name server for the 15.0.168.192.in-addr.arpa record.

In a Local Area Network (LAN), each device is assigned an IP address which is used to identify it. These IP addresses are often dynamic and can change over time. However, each device also has a unique computer name that remains constant. This article will guide you on how to find a computer name from an IP address in a LAN using various methods.

To find a computer name from an IP address in a LAN, you can use various methods such as using nmap, nmblookup, nslookup, checking the DHCP server, or using nbtstat (Windows only). These methods allow you to query the network and retrieve the computer name associated with a specific IP address.

Using nmap
Using nmblookup
Using nslookup
Checking the DHCP Server
Using nbtstat (Windows Only)
Conclusion

Using nmap

nmap is a powerful network scanning tool that can be used to discover hosts and services on a computer network. It can also be used to find a computer name from an IP address.

To use nmap, open your terminal and type the following command:

sudo nmap -sn <Your LAN Subnet>

For example:

sudo nmap -sn 192.168.1.*

The -sn option tells nmap to perform a simple ping scan, which is used to find up hosts without port scanning them. The * in the subnet is a wildcard that represents all possible IP addresses within the subnet.

This command will return a list of all active devices on your LAN, along with their IP addresses and hostnames.

Using nmblookup

nmblookup is a tool used to query NetBIOS names and map them to IP addresses in a LAN. It can be used to find a computer name from an IP address.

To use nmblookup, open your terminal and type the following command:

nmblookup -A <IP address>

For example:

nmblookup -A 192.168.1.2

The -A option tells nmblookup to perform a node status query on the specified IP address. This will return the NetBIOS name of the device, along with other information such as the device type and MAC address.

Using nslookup

nslookup is a network utility program used to obtain information about Internet servers. It can be used to find a computer name from an IP address.

To use nslookup, open your terminal and type the following command:

nslookup <IP address>

For example:

nslookup 192.168.1.2

This command will return the DNS hostname for the specified IP address.

Checking the DHCP Server

Most LANs use a DHCP server to dynamically assign IP addresses to devices. These servers often keep a record of the IP addresses they have assigned, along with the corresponding computer names.

To check the DHCP server, you will need to access its administrative interface. This is often a web page that can be accessed by typing the IP address of the DHCP server into your web browser. The exact method for accessing this information will vary depending on the make and model of your DHCP server.

Using nbtstat (Windows Only)

If you are using a Windows machine, you can use the nbtstat command to find a computer name from an IP address.

Open your command prompt and type the following command:

nbtstat -A <IP address>

For example:

nbtstat -A 192.168.1.2

The -A option tells nbtstat to display the NetBIOS name table of the remote computer specified by the IP address.

This command will return the NetBIOS name of the device, along with other information such as the device type and MAC address.

Conclusion

Finding a computer name from an IP address in a LAN can be done using a variety of methods. The method you choose will depend on your specific network configuration and the tools you have available. By following the steps outlined in this article, you should be able to find the computer name associated with any IP address on your LAN.

Yes, you can use nmap to find the computer name from an IP address in a LAN. Simply open your terminal and run the command sudo nmap -sn <Your LAN Subnet>. This will perform a simple ping scan and return a list of active devices on your LAN, including their IP addresses and hostnames.

No, nmblookup is not limited to Linux systems. It is a tool used to query NetBIOS names and map them to IP addresses in a LAN, and it is available for multiple operating systems, including Linux, macOS, and Windows.

Yes, you can use nslookup to find the computer name from an IP address in a LAN. Open your terminal and run the command nslookup <IP address>. This will return the DNS hostname for the specified IP address.

Yes, if you are using a Windows machine, you can use the nbtstat command to find the computer name from an IP address. Open your command prompt and run the command nbtstat -A <IP address>. This will display the NetBIOS name table of the remote computer specified by the IP address.

This article explains how to find out the hostname of a computer connected to a local network using the IP address. Depending on the type of IP address — public or private — there are two different procedures. Here we will give an easy hint on how to do this.

How to find a hostname via public IP address?

In order to find the hostname of a computer with a public IP address, you have to pass the address to the Domain Name System (DNS) server. Here are the steps to follow:

Click on the Window Start button.
Click on “All Programs”.
Click on “Accessories”.
Right-click on «Command Prompt«.
Choose «Run as Administrator«.
Type “nbtstat -a <ip_address>”. Note that <ip_address> is the IP address of the computer.

How to find a hostname via private IP address?

Finding the hostname of a computer with a private IP address and no local DNS server means you need to query the host itself by using a Windows utility. Here are the steps to follow:

Click on the Window Start button.
Click on “All Programs”.
Click on “Accessories”.
A black box opens.
Type «nslookup -a <ip_address>«. Note that <ip_address> is the IP address of the computer.

Note that it is not necessary to know an IP address in order to find other systems if you have a WiFi LAN connection.

We hope that you find these solutions useful and that your question is answered!

У меня в домене есть «плавающий» ip, который статически может быть назначен одному любому компу в локальной сети. Это делается по служебной необходимости. Делается это руками. Написал программу-«датчик», которая пингует этот адрес и в трее показывает, занят этот адрес или нет (как светофор — зелёный — не занят, красный — занят). Этот адрес всегда назначается только компьютеру. Соответственно у компьютера есть имя, которое я хочу определить и вывести в tooltip, чтобы можно было навести и посмотреть — у кого этот адрес. Нашёл, что существует несколько способов определения имени компа, например:

Dns.GetHostEntry

[DllImport(«Netapi32.dll», CharSet = CharSet.Unicode, ExactSpelling = true)]
public extern static IntPtr NetWkstaGetInfo(string servername, int level, ref IntPtr bufptr);

[DllImport(«IpHlpApi.dll»)]
[return: MarshalAs(UnmanagedType.U4)]
static extern int GetIpNetTable(IntPtr pIpNetTable, [MarshalAs(UnmanagedType.U4)] ref int pdwSize, bool bOrder);

Но так же пишут, что эти методы не дают 100% результата определения имени компьютера по ip. Поэтому этими методы я перебираю по очереди, когда предыдущий метод не смог определить имя компьютера. Но всё равно бывают ситуации, когда ни один из методов не определил имя компьютера. И я бы сильно по этому поводу не переживал, если бы только не программа

nbtstat -a [ip]

которая всегда находит правильное имя компа, когда мои методы не дают результата. Не подскажите, чем бы ещё воспользоваться? Функция или библиотека какая-нибудь (запуск nbtstat — не предлагать).
