Default DNS Servers

I updated firmware on a TZ270 to 7.1.1-7051 and then booted to factory default configuration.

I noticed the default DNS servers are set at:, and

The first 2 are a mystery to me and seems strange that the Sonicwall would have Specify DNS Servers Manually set to those. Does anybody have an idea of what those 2 ip addresses are?

    @MikeSun this is part of the new DNS Security which came with SonicOS 7.1.1. It's powered by Vercara and might be their product UltraDNS used for DNS resolving. I'am not 100% sure if it's used for CFS 5.0 as well.

    Having not jumped to 7.1.1, but cognizant of the new DNS feature, I'm grateful to both of you for pointing this out.
