IPCONFIG

Ipconfig/ifconfig Command

• What does Internet Protocol Configuration (Ipconfig) mean?
• Internet Protocol Configuration (ipconfig) is a Windows console application/tool that has the ability to gather all data regarding current Transmission Control Protocol/Internet Protocol (TCP/IP) configuration values and then display this data on a screen. 
• Ipconfig also refreshes the Domain Name System (DNS) and Dynamic Host Configuration Protocol (DHCP) settings each time it is invoked. 
• One of the most important things that must be completed when troubleshooting a networking issue is to find out the specific IP configuration of the variously affected hosts. 
• Sometimes this information is already known when addressing is configured statically, but when a dynamic addressing method is used, the IP address of each host can potentially change often. 
• The utilities that can be used to find out this IP configuration information include the ipconfig utility on Windows machines and the ifconfig utility on Linux based machines.
