The default IP version setting for sending or receiving DNS Proxy Packets is IPv4 to IPv4. This is significant because DNS, or Domain Name System, traditionally operates over IPv4, which has been the predominant version of the Internet Protocol used for most web traffic and peer communications.

By keeping the configuration set to IPv4, it ensures compatibility and reduces complexity within the network setup, especially for devices that predominantly communicate using IPv4 addresses. This setting facilitates efficient and reliable DNS resolutions, as most networks still heavily rely on IPv4 architecture.

While IPv6 adoption is growing and there are scenarios where IPv6 DNS queries are necessary, IPv4 remains the standard upon which many organizations and configurations are primarily built, making the IPv4 to IPv4 setting a pragmatic choice for default operations.
