Release/Renew IP and Flush DNS

When you connect to a new website or server, your computer takes time to look up the necessary information to create the connection. This information is locally stored for future re-use, which makes the next connection to the same IP address much faster.

Connectivity issues, like disconnection or lag, typically occur due to IP-related problems, such as:

• Expired IP configurations
• IP address conflicts
• Errors that occur while trying to establish a connection with a game server

Refreshing your internet connection by releasing and renewing your IP address and flushing your Domain Name System (DNS) cache can fix these connectivity issues.

To see how to troubleshoot connectivity issues, watch our video on YouTube (see below).

Release/renew IP

Releasing your IP frees the address from your router and drops your internet connection. Renewing your IP either reassigns your current address (if it is still available), or assigns a new address to your computer, allowing you to reconnect to the internet.

Flush DNS

DNS turns domain names (for example, www.nexon.com) into an IP address (for example, 13.33.21.118) so that browsers can access websites and other internet resources. Flushing DNS cache can clear any obsolete entries, which can improve your connection.

Releasing, renewing, and flushing IP and DNS information

To release and renew your IP address and flush the DNS:

1. From the Start menu, type cmd to search for the Command Prompt app.
2. Select Run as administrator.
   
   
   
3. Click Yes to allow User Account Control (UAC), if prompted.
   
   
   The Administrator: Command Prompt window opens.
   
   
4. At the prompt, type ipconfig /release, and then press Enter.
   
   
   The command now executes. You may see several lines of text before the command prompt returns.

5. At the prompt, type ipconfig /renew, and then press Enter.
   
   
   The command now executes. You may see several lines of text before the command prompt returns.

6. At the prompt, type ipconfig /flushdns, and then press Enter.
   
   
   The command now executes.

7. Close the Command Prompt and restart your computer to ensure that the changes take effect.

You can now reconnect to the internet.
