Ping returns IPv6 Address, ping IPv4?

If you are on the same network, or VLAN, or subnet as someone else – you will probably notice that if you ping their hostname it will return with a IPv6 address.

Ping srv01
Pinging [fe80::c09::d4e6::189f::f661%3] with 32 bytes of data

ping ipv4

The fact is that the IPv6 protocol in Windows Vista and above is the preferred protocol over IPv4.

If you want to still see what’s their IPv4 address, then simply use the command below:

ping hostname -4

Simply add a flag “-4” after your normal ping command:

Ping srv01 -4
Pinging [] with 32 bytes of data
Reply from bytes=32 time<1ms TTL=128

ping ipv4 cmd

As you can see, ping command returned standard IPv4 address.

In the event that, when the client requests the server and it returns the IPv6 address, and there are some problems with the operation of some legacy applications, there is a more advanced solution.

The solution is to increase the priority of the IPv4 over the IPv6 protocol, but with the continued operation of IPv6.

The solution doesn’t require reboot, it takes effect immediately. You need to open an elevated Command Prompt, and execute 2 commands:

netsh interface ipv6 set prefix ::/96 60 3
netsh interface ipv6 set prefix ::ffff:0:0/96 55 4

On an example of a clean Windows Server 2016, execute these two commands and check ping again:

Pinging [] with 32 bytes of data
Reply from bytes=32 time<1ms TTL=128
Reply from bytes=32 time<1ms TTL=128

ping return ipv4

As you can see, the result changed dramatically in the direction we needed, the IPv4 address began to return. Now we’ll check that the server is still pinging using its IPv6 address, and we didn’t break anything:

ping fe80::c09::d4e6:189f:f661%3

ping ipv4 command line

Everything works as it should be.

You can also change preferred IP protocol from GUI. To do it, open Control Panel -> Network and Internet -> Network Connections -> Advanced -> Advanced Settings.

Tip. Adapters and Bindings dialog box is missing in a newest Windows 10/Windows Server 2016.

how to ping ipv4

Select your network connection and using green button set the IPv4 protocol above IPv6. You should perform this operation for all available bindings.

    is there a way to change it so that it responds on IPv4, by default? I don’t want to disable IPv6, but do not want to use it at all

    • Brian Jackson

      If you are not using IPv6 there is no reason to have it enabled. To disable it, go to Network Connections, right click Properties on your NIC and then uncheck “Internet Protocol Version 6 (TCP/IPv6).
      Hope that helps! There is no way unfortunately to default to IPv4 like in command prompt.

      • Ronny Ong

        Unchecking the protocol binding is not sufficient to disable IPv6. It will seem to work at first, but you will eventually run into strange network problems that seem to defy any explanation. This is ESPECIALLY true for servers. To properly disable IPv6, see KB929852. The “Fix It” MSI available from this KB article is suitable for GPO deployment, no need to create a custom ADMX.

        That does not disable IPv6 totally. You can do the following to disable it totally: Create a DWORD entry named DisabledComponents in HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpip6Parameters and give it the value 0xffffffff
