What is traceroute?
Traceroute is a widely used command line utility available in almost all operating systems. It shows you the complete route to a destination address. It also shows the time taken (or delays) between intermediate routers. Isn’t it great? Below is an example on Windows operating System.
Ping is a basic Internet program that allows a user to verify that a particular IP address exists and can accept requests.
ipconfig
Ipconfig (sometimes written as IPCONFIG) is a command line tool used to control the network connections on Windows NT/2000/XP machines. There are three main commands: "all", "release", and "renew". Ipconfig displays all current TCP/IP network configuration values and refreshes Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS) settings. Used without parameters, ipconfig displays the IP address, subnet mask, and default gateway for all adapters.
nslookup
nslookup is the name of a program that lets an Internet server administrator or any computer user enter a host name (for example, "whatis.com") and find out the corresponding IP address or domain name system (DNS) record. The user can also enter a command for it to do a reverse DNS lookup and find the host name for an IP address that is specified.
