![]() Managing network communications in a world that straddles IPv4 and IPv6 can be challenging. This command sets the precedence for IPv4 back to its default value, thus prioritizing IPv6 over IPv4 again. If at any point you wish to revert to the default settings and prioritize IPv6 over IPv4, you can do so with the following command: netsh interface ipv6 set prefixpolicy ::ffff:0:0/96 35 4 Learn more: How to Use Netsh Interface IP Set Address or DNS in CMD Please note that altering prefix policies can have wide-ranging effects on your network connections and should be done with care. If you run the “show prefixpolicies” command again, you should now see that the IPv4 has a higher precedence.This command sets the precedence of IPv4 (::ffff:0:0/96) to a higher value than the default IPv6 precedence. Netsh interface ipv6 set prefixpolicy ::ffff:0:0/96 60 4 This can be done using the following command: To prefer IPv4 over IPv6, we need to increase the precedence of IPv4.Higher precedence values mean higher priority. The output will show a list of prefix policies with different precedence levels. Type the following command to see the current prefix policies:.You can do this by searching for “cmd” in the Start menu, right-clicking on Command Prompt, and selecting “Run as administrator”. Open the Command Prompt with administrative privileges.However, you can alter these policies to prefer IPv4.įollow the steps below to prefer IPv4 over IPv6: By default, Windows prefers IPv6 over IPv4. The prefix policy table in Windows dictates the preference of IP addresses when initiating a connection. This can be achieved in Windows by altering the prefix policies. While using the “-4” switch with the ping command is a handy tool for one-off commands, you might find yourself in a situation where you need to prefer IPv4 over IPv6 for all connections. How to prefer IPv4 over IPv6 in Windows 11/10 This command will force the ping to use IPv6. The ping command in Windows offers a “-6” switch for this purpose: ping -6 Replace “with the hostname or IP address you want to ping. Useful tip: How to Find The IP Address of a Website in Windows 11 Pinging using IPv6 Instead of IPv4Ĭonversely, there may be situations where you specifically want to ping IPv6 address instead of IPv4, such as testing IPv6 connectivity or functionality. Here’s how: ping -4 In this example, replace “with the hostname or IP address you want to ping. This switch forces the system to use IPv4 for that specific ping command. To ensure that your system pings using IPv4, you can use the “-4” switch. As a result, when you try to ping a hostname, the returned address might be IPv6 even if an IPv4 address is also available. This is in line with the global movement towards IPv6. Windows operating systems, including Windows 10 and 11, typically prefer IPv6 when both protocols are available.

Troubleshooting: Connectivity issues can occur in mixed environments.Interoperability testing: If you’re managing a network transitioning from IPv4 to IPv6, you may need to ensure that your new IPv6 devices can communicate with older IPv4 devices.Pinging an IPv4 address from an IPv6 network could be crucial for several reasons: With the continuing existence of IPv4 in many parts of the internet, the need to ping an IPv4 address from an IPv6 network arises. However, the reality of this transition isn’t as smooth as we would like. ![]() In an ideal scenario, IPv6 should seamlessly supersede IPv4 without causing any hitches in network operations. Why ping an IPv4 address from an IPv6 network?
