Linux DNS问题

我按照几篇网上的文章配置了dns，但是启动时报错。该怎么解决？
named配置错误：:
localhost.zone:1: unknown RR type '192.168.20.253'
zone localhost/IN: loading master file localhost.zone: unknown class/type
_default/localhost/IN: unknown class/type
testa.com:2: unknown RR type 'IN?SOA'
dns_master_load: testa.com:12: unexpected end of line
dns_master_load: testa.com:11: unexpected end of input
zone testa.com/IN: loading master file testa.com: unknown class/type
_default/testa.com/IN: unknown class/type

以后有Linux的问题的话， 可以发私信， 不过这个问题wo是很久没有弄了
