How to know information about IP from internal network

If you want to gather information about an IP address internally (within your own network or system), you can use various methods and tools. Here’s how to do it:

1. Ping Command: You can use the ping command in your command prompt or terminal to check if an IP address is reachable and gather basic information such as response times. For example: ping 192.168.1.1.
2. Traceroute/Tracepath: Use the traceroute command on Unix-based systems or tracert on Windows to trace the route that packets take to reach a destination IP address. This can help you understand the network path to the target.
3. ARP Table: To find information about devices within your local network, you can use the arp -a command (on Windows) or arp -n (on Unix-based systems) to display the ARP (Address Resolution Protocol) table, which maps IP addresses to MAC addresses on your local network.
4. Netstat: The netstat command can provide information about active network connections, listening ports, and routing tables on your system. For example, netstat -nr will display the routing table.
5. Nmap: If you want to perform a more in-depth scan of devices on your network, you can use a tool like Nmap. This tool can provide detailed information about open ports, services, and more.
6. Network Configuration Files: Check your system’s network configuration files. For example, on Linux, you can look at /etc/network/interfaces or /etc/sysconfig/network-scripts/ifcfg-eth0 to find information about IP addresses and network settings.
7. GUI Network Utilities: Many operating systems offer graphical network utilities that provide information about network devices, IP addresses, and connections. These utilities are often more user-friendly than command-line tools.

Remember that gathering information about IP addresses on a network may be subject to network policies and permissions.

Always ensure you have the necessary rights and permissions before attempting to access or gather information about IP addresses within a network.
