It means that your network is misconfigured.... Read RFC 1918 for details

Its not really new...

You have a DNS "leak"... To partially solve your problem, you need to configure
your internal dns servers as authoritive for the private range so that the
192.168 reverse lookups dont go out to the internet (if they do, you get that as
the response).. Then you need to configure all devices that use dns to use the
internal DNS server(s) for look ups....
