ipconfig command snippets

Copy-paste-ready ipconfig commands for viewing DNS cache, flushing DNS records, and managing network configuration on Windows.

View the DNS Resolver Cache with ipconfig

ipconfig displays all cached DNS entries stored on the local computer with the /displaydns parameter. Each entry shows the domain name, record type, Time to Live (TTL), and the resolved IP address.

ipconfig /displaydns

Run /displaydns in Windows Command Prompt:

  1. Type cmd in the Windows search bar to open the Command Prompt app:

    ipconfig open command prompt app

  2. Type ipconfig /displaydns and press Enter:

    ipconfig displaydns command highlighted with results

Flush the DNS Resolver Cache with ipconfig

ipconfig clears all cached DNS entries from the local DNS resolver with the /flushdns parameter. This forces Windows to fetch fresh DNS records from the configured DNS server on the next domain lookup.

ipconfig /flushdns

Run /flushdns in Windows Command Prompt:

  1. Type cmd in the Windows search bar to open the Command Prompt app:

    ipconfig open command prompt app

  2. Type ipconfig /flushdns and press Enter:

    ipconfig flushdns command highlighted with results

  3. ipconfig confirms the operation with a "Successfully flushed the DNS Resolver Cache" message.

Release and Renew a DHCP Lease with ipconfig

ipconfig releases the current DHCP lease and requests a new IP address from the DHCP server. Run these two commands in sequence to resolve DHCP-related connectivity issues.

ipconfig /release
ipconfig /renew

Display Full TCP/IP Configuration with ipconfig

ipconfig displays the complete TCP/IP configuration for all network adapters with the /all parameter. The output includes the MAC address, DHCP status, DNS servers, and lease timestamps.

ipconfig /all
