BIND 9.5.1 的新特性？ 问题

北京二胖

内部PC ip地址是10.0.7.53 安装BIND 9.5.1 作为DNS 服务器
MAP到互联网的ip是 219.143.1.1

在10.0.7.53 上设置主DNS为 219.143.1.1


1、用WINDOWS默认的nslookup 工具

> www.sina.com.cn
Server:  UnKnown
Address:  218.247.19.41

DNS request timed out.
    timeout was 2 seconds.
DNS request timed out.
    timeout was 2 seconds.
*** Request to UnKnown timed-out



2、用BIND 的dig工具

dig  www.sina.com.cn

;; reply from unexpected source: 10.0.7.53#53, expected 218.247.19.41#53
;; reply from unexpected source: 10.0.7.53#53, expected 218.247.19.41#53
;; reply from unexpected source: 10.0.7.53#53, expected 218.247.19.41#53

; <<>> DiG 9.5.0-P1 <<>>
;; global options:  printcmd
;; connection timed out; no servers could be reached


请问这是新特性吗，查询回复的源ip必须是设置的dns服务器IP？
