NEWBIE : No default TTL messages

[Mohd Fared Bin Abdul Khir]

Hi,
I've just installed bind8.2.1 on a sunos4.x machine.
I'm getting these below messages at /var/adm/messages 
when booting up named.
any suggestion ?

Aug 27 10:46:35 foo named[20976]: Zone "0.0.127.IN-ADDR.ARPA" (file
named.local): No default TTL set using SOA minimum instead

thank you very much,
