Take a look at your ARM (Administrator Resource Manual) usually 
found in /usr/share/doc/bind-your_version/arm and look for 
something like the following:

max-ncache-ttl

    To reduce network traffic and increase performance the server 
stores negative answers. max-ncache-ttl is used to set a maximum 
retention time for these answers in the server in seconds. The 
default max-ncache-ttl is 10800 seconds (3 hours). max-ncache-ttl 
cannot exceed 7 days and will be silently truncated to 7 days if 
set to a greater value.
