     6The solution doesn’t require a reboot, it takes effect immediately. You need to open an elevated Command Prompt, and run 2 commands:
     7
     8netsh interface ipv6 set prefix ::/96 60 3
     9
     10netsh interface ipv6 set prefix ::ffff:0:0/96 55 4
     11
     12These commands increased the priority of the IPv4 prefix policy and decreased the priority for IPv6. By default, this change is made persistent across reboots.
     13
     14For example, run these two commands on a clean Windows Server 2016 host, and run a ping request again:
     15
     16Pinging srv01.contoso.com [192.168.10.21] with 32 bytes of data

     18Reply from 192.168.10.21: bytes=32 time<1ms TTL=128
