How to find ip address of Server in Linux?

Finding the IP Address of a Server in Linux

In this article, we will explore the various ways to find the IP address of a server running on a Linux system. This is an essential step in troubleshooting and debugging server issues.

Method 1: Using the ip Command

The ip command is a powerful tool for managing IP addresses and networks on Linux systems. Here’s how to use it to find the IP address of a server:

• Accessing the IP Address of a Server

  To access the IP address of a server, you can use the ip command with the -4 option, which specifies that you want to view the IP address in IPv4 format. You can also use the -6 option to view the IP address in IPv6 format.

  ip addr show

  This command will display the IP address of the server in both IPv4 and IPv6 formats.

• Finding the IP Address of a Server by IP Address

  You can also use the ip command to find the IP address of a server by its IP address. To do this, you can use the -4 or -6 option, followed by the IP address.

  ip addr show 192.168.1.100

  This command will display the IP address of the server with the specified IP address.

Method 2: Using the ifconfig Command

The ifconfig command is another powerful tool for managing IP addresses and networks on Linux systems. Here’s how to use it to find the IP address of a server:

• Accessing the IP Address of a Server

  To access the IP address of a server, you can use the ifconfig command with the -a option, which specifies that you want to view all network interfaces.

  ifconfig

  This command will display the IP address of all network interfaces on the server.

• Finding the IP Address of a Server by Interface

  You can also use the ifconfig command to find the IP address of a server by its interface. To do this, you can use the -a option followed by the interface name.

  ifconfig eth0

  This command will display the IP address of the interface with the specified name.

Method 3: Using the hostname Command

The hostname command is a built-in command on Linux systems that displays the hostname of the server. Here’s how to use it to find the IP address of a server:

• Accessing the IP Address of a Server

  To access the IP address of a server, you can use the hostname command with the -n option, which specifies that you want to view the hostname instead of the IP address.

  hostname -n

  This command will display the hostname of the server.

• Finding the IP Address of a Server by Hostname

  You can also use the hostname command to find the IP address of a server by its hostname. To do this, you can use the -n option followed by the hostname.

  hostname myserver

  This command will display the IP address of the server with the specified hostname.

Method 4: Using the ip addr Command with grep

The ip addr command is a powerful tool for managing IP addresses and networks on Linux systems. Here’s how to use it to find the IP address of a server:

• Accessing the IP Address of a Server

  To access the IP address of a server, you can use the ip addr command with the -4 or -6 option, followed by the IP address.

  ip addr show 192.168.1.100 -4

  This command will display the IP address of the server with the specified IP address.

• Finding the IP Address of a Server by IP Address

  You can also use the ip addr command to find the IP address of a server by its IP address. To do this, you can use the -4 or -6 option followed by the IP address.

  ip addr show 192.168.1.100 -4

  This command will display the IP address of the server with the specified IP address.

Method 5: Using the ifconfig Command with grep

The ifconfig command is another powerful tool for managing IP addresses and networks on Linux systems. Here’s how to use it to find the IP address of a server:

• Accessing the IP Address of a Server

  To access the IP address of a server, you can use the ifconfig command with the -a option, followed by the IP address.

  ifconfig eth0 -a 192.168.1.100

  This command will display the IP address of the interface with the specified name.

• Finding the IP Address of a Server by Interface

  You can also use the ifconfig command to find the IP address of a server by its interface. To do this, you can use the -a option followed by the interface name.

  ifconfig eth0 -a 192.168.1.100

  This command will display the IP address of the interface with the specified name.
