There is no such hard and fast rule for using the ipconfig command. There is a simple way to use it and that is to type them in PowerShell and execute them. However, information about when and how to use them can be obtained. Thus, the list of ipconfig commands along with their practical usage and information is given below.

1. ipconfig /all

The ipconfig /all command gets all IP configurations. It lists all network adapters, including wireless networks and wired LAN networks. This displays the configuration of each connected adapter. Network configuration includes details of media status, physical address, or DHCP status.

Example:

The ipconfig /all command gets the configuration of the TCP/IP adapter:

Example:

To get the cached DNS details, execute the following command in the PowerShell console:

3. ipconfig /flushdns

The ipconfig /flushdns command clears the DNS resolver cache. This clears locally cached DNS records. Even though Windows clears cached DNS records automatically. But, this can be cleared manually with a single ipconfig /flushdns command.

Example:

To manually clear cached DNS records, type and run this command:

4. ipconfig /registerdns

The ipconfig /registerdns command creates or registers a DNS server. It does this by using the hostname and IP address of the computer on which the command is being executed. This informs the DNS server to register or update the DNS record for the current computer.

Example:
