To check the IP address of a domain name using Linux

To check the IP address of a domain name using Linux, you can use several tools such as nslookup, dig or host. Here are some examples:

Using nslookup:

nslookup example.com

This command will return the IP address associated with the domain name "example.com”.

Using dig:

dig example.com

This command will also return the IP address associated with the domain name "example.com”, along with additional information about the DNS server.

Using host:

host example.com

This command will also return the IP address associated with the domain name "example.com”, along with additional information about the DNS server.

Note that in order to use these commands, you may need to have the necessary tools installed on your Linux system. Additionally, depending on your specific Linux distribution or version, the commands or their output may differ slightly.
