For troubleshooting network issues, which command is useful for checking the server's IP address?

1. ipconfig

2. ifconfig

3. ping

4. nslookup

The correct answer is: nslookup

The command that is particularly useful for checking a server's IP address is typically associated with obtaining the network configuration details of a machine. In the context of Windows systems, the command "ipconfig" retrieves the IP address, subnet mask, and default gateway for all network adapters on the host. This makes it a direct and practical tool for troubleshooting network issues related to the server's IP address. While "ifconfig" serves a similar purpose in Unix/Linux systems, it is not relevant to Windows environments, which further emphasizes the direct applicability of "ipconfig" for checking IP addresses on those systems. "Ping" is a command used to test connectivity to a host but does not provide information about the host's IP address itself, nor does "nslookup", which is more focused on domain name resolution rather than current IP configuration. Understanding the appropriate tool to check for an IP address based on the operating system in use is crucial for effective network troubleshooting.
