The TTL for news.google.com is set to 5 minutes. However, google
sets the TTL for their nameservers to be 4 days, but RR's
configuration limits the max TTL to 24 hours. From my vantage
point, the DNS server does cache the results. What are you seeing
that I am not?

I have never seen a utility that queries DNS in such a way.
I use dig to troubleshoot DNS myself.
