Ipconfigi

Ipconfigi is a command-line utility used on Microsoft Windows operating systems. Its primary function is to display current TCP/IP network configuration values and to refresh Dynamic Host Configuration Protocol (DHCP) and Domain Name System (DNS) settings. When executed, ipconfigi provides information such as the IP address, subnet mask, and default gateway for each network adapter present on the system.

Beyond simply displaying information, ipconfigi can also be used to perform network troubleshooting. The command ipconfigi /release is used to release the current IP address obtained from a DHCP server. Conversely, ipconfigi /renew will request a new IP address from the DHCP server. Another common option is ipconfigi /flushdns, which clears the DNS resolver cache. This can be useful when DNS records have changed and the system is still using outdated information.

The utility is accessed by opening a command prompt window and typing "ipconfigi" followed by any desired parameters. For instance, typing "ipconfigi /all" provides more detailed information, including MAC addresses, DNS server addresses, and whether the IP address is assigned automatically via DHCP. Understanding and utilizing ipconfigi can be a fundamental step for network administrators and users alike when diagnosing and resolving network connectivity issues.
