Hi!

I use Bind9 and I perceived the cache don't keep the information in
memory at the time imposed by master server of the remote zone. Example:

--------------------------
# dig www.terra.com.br @ns1.terra.com.br

; <<>> DiG 9.3.4 <<>> www.terra.com.br @ns1.terra.com.br

...

;; ANSWER SECTION:
www.terra.com.br. 7200 IN A 200.176.3.142

...
--------------------------

I think this information must be kept in the local DNS cache by 7200
seconds. However, if I call www.terra.com.br in the browser and I wait
ten minutes and I try to access the URL again, the browser shows
"searching www.terra.com.br". Why?
