Are you trying to find dns caches provided by your ISP? If so you
should check out their support. Often that information is provided
as part of dhcp handshake. It may also be an FAQ.

dig, nslookup, dnsqr and dnsq (the latter two don't come with FC) allow
you to do this. The problem is that you need to know who to ask.
Normally your ISP will supply a pair of recursive resolver and cache
servers to answer these questions for you.

It is possible to run your own cache and resolver instead. It works by
having a list of the root dns servers and will start there to get answers
to questions for which it doesn't have the answers.
