After upgrading to Windows 10, I noticed that my computer had a different DHCP lease time than other Windows 7 computers in the same network. How to change DHCP lease time windows 10?
Lease times for dynamic IP addresses vary according to your default gateway/router settings. On most residential routers, it is good to have a shorter lease time if the router reboots. The shorter lease time will have less chance of a conflict with a computer that is trying to renew at the same time as the reboot. Read more: How to Use Kmspico to Activate Windows and Office Program
How to change DHCP lease time windows 10?
To view and configure the Windows 10 DHCP lease time:
1. On your keyboard, press the Windows logo key and R at the same time to invoke a Run command.
2. Type in “cmd” (without quotes) in the text field and press Enter on your keyboard. Note: If you prefer, you can use a third-party utility such as NirSoft’s NetScanTool to display the advanced IP configuration of your network adapter.
3. Type in “ipconfig /all” (without quotes) and press Enter on your keyboard. Note: The Windows 10 DHCP lease time is currently set at 8 days for most home networks, but you can also see it from the image from step 1.
4. Type in “netsh” (without quotes) in the text field and press Enter on your keyboard.
5. Type in “interface ip show dhcpserver” (without quotes) in the text field and press Enter on your keyboard. Note: As you can see, there are two DHCP servers on my home network. You will see only one server if you are using a single router for your home network.
6. Type in “interface ip show dhcpserver 0” (without quotes) and press Enter on your keyboard to view the configuration of DHCP server 0 (which is currently turned off). Note: If you want to edit the DHCP lease time for this particular DHCP server, type in “set optionvalue 0 DHCPServerOptionInitialPeriod 15” (without quotes) and press Enter on your keyboard.
7. Repeat steps 5 and 6 if you want to change the DHCP lease time for any two servers. Note: For those interested, you can also configure the DNS settings for the DHCP server using this command “set optionvalue 0 DHCPServerOptionDNSServerSearchOrder 192.168.1.100” (without quotes). Press Enter on your keyboard to save the changes.
8 . Type in “exit” (without quotes) and press Enter to close the window on your keyboard.
9. Type in “exit” (without quotes) and press Enter on your keyboard to close the prompt as well. Note: In case you do not want to keep these changes, use this command ” netsh interface ip show dhcpserver 0 ” to display the current configuration, then type in “delete optionvalue 0 DHCPServerOptionDNSServerSearchOrder” (without quotes). Press Enter on your keyboard to delete the DNS settings.
10 . That’s it! You are done.
DHCP lease time is one of those things that can be configured. In most home networks, leases are set at 8 days by default. This is a good compromise between having computers get addresses quickly and having enough time for a router to inform a computer about the change in case the address changes.
If you do not want your computers to auto-configure every 8 days, you can reduce that. You may want to try 3 or 7 days if you feel you need the extra time. If your router is one of those that reboots on its own, then it would be a good idea to set the DHCP lease time higher than the reboot interval (usually 24 hours).
