Network Utility Tools are one of the most needed tools in order to have a quick diagnosis of your network. Whether you want to check the information for your network connections, its status or resolve and troubleshoot any connectivity issues, Network Utility Tools will be the handiest to overcome this matters.
So here we will discuss some of the Network Utility Tools that can work across platforms of Mac, Windows, and Linux.
This tool is one of the most widely used tools to check the connectivity between two different hosts. Using the Internet Control Message Protocol (ICMP), Ping will help you know the connectivity with the destination through an echo request.
You can Ping to a particular domain name or an IP address in order to determine whether your TCP/IP is installed and properly configured on your local computer. Ping will send packets to the destination, which will then respond to its own packets. Ping also lets you see the round-trip-time between your computer and the destination.
In case your computer is not able to communicate with the remote host, you will get an error message. And in case if the packet loss is occurring, you get the “request timed out” message.
IPConfig or IFConfig
This command helps you check the information of your network and also configure them when required. ipconfig command is used on Windows operating system while Mac, Linux, and other system show the network information through the ifconfig command. Using only the ipconfig command you can get a quick information regarding your IP address, subnet mask, and the default gateway.
However, using the ipconfig/all command, you can check detailed information like all the configured network interfaces and their IP addresses, DNS servers, Mac Addresses and other similar information.
netstat stands for network statistics. It lets you check the network statistics, information regarding several incoming and outgoing connections routing tables, as well as other network connections.
Using this utility tool, you can check the number of open connections to your computer, specific programs that make different connections, the amount of data being transmitted and other similar information.
This command works very much similar to Ping and will provide you with information regarding the path the packet takes. While sending packets to the destination, it will communicate with each of the Internet routers along the way.
This way, you can trace the path these packets take while traveling from your location to your destination. This makes it easy to troubleshoot and check the connection problems and failures. Any information that is sent from the source computer will travel through other connected servers, computers, and routers before reaching the destination.
This network utility tool is used to diagnose problems that are associated with the Address Resolution Protocol (ARP).
ARP is used by the TCP/IP to determine a particular Mac Address corresponding to a specific IP address. By typing the arp -a option, you can quickly determine the IP address that has been used in order to resolve the Mac address recently.
This command helps you to check the IP address associated with a particular domain name. For example, the command nslookup espn.com lets you see the IP address associated with ESPN’s server.
During normal operations, your computer insists your DNS servers to translate domain names to IP address, This command lets you do that manually.
Using this command, you can also perform reverse operations like convert IP address to domain name. For example, nslookup 18.104.22.168 will tell that this IP address is associated with espn.com.
