我的DNS伺服器用「host」命令測試時是正確的，但後面測試就變成不對了！很不理解怎麼回事？！
我的主機的IP：192.168.0.1
我的VM虛擬機的IP：192.168.0.99
為什麼會有這樣的怪問題呢？
# host www.happy.com （執行正向查詢命令）
www.happy.com has address 192.168.0.1
# host 192.168.0.1 （執行反向查詢命令）-------------這是正確的！！！！！
1.0.168.192.in-addr.arpa domain name pointer www.happy.com.
1.0.168.192.in-addr.arpa domain name pointer dns.happy.com.
# host -t NS happy.com （查詢NS）
happy.com name server dns.happy.com.
# host -t SOA happy.com （查詢SOA的A記錄）
happy.com SOA dns.happy.com. root.happy.com. 42 10800 900 604800 86400
第一次測試沒問題！第二次我測試時，反向的測試變成了「DEll.mshome.net.」？很不理解？
# host www.happy.com
www.happy.com has address 192.168.0.1
# host 192.168.0.1 ------------------這就不對了（DELL是我的電腦的名字）
1.0.168.192.in-addr.arpa domain name pointer DEll.mshome.net.
# host -t NS happy.com
happy.com name server dns.happy.com.
# host -t SOA happy.com
happy.com SOA dns.happy.com. root.happy.com. 42 10800 900 604800 86400
其他都是對的！為什麼反向解析會變成DEll.mshome.net.呢？怎麼使它正確呢？！！！！

請高手快幫幫忙看看吧！謝謝！！！！！！:lol:

這是我的反向解析配置文件：
$TTL 86400
@ IN SOA dns.happy.com. root.happy.com. (
1997022700 ; Serial
28800 ; Refresh
14400 ; Retry
3600000 ; Expire
86400 ) ; Minimum
IN NS dns.happy.com.
1 IN PTR dns.happy.com.
1 IN PTR www.happy.com.
~
這是我的正向解析文件：
$TTL 86400
@ IN SOA dns.happy.com. root.happy.com. (
42 ; serial (d. adams)
3H ; refresh
15M ; retry
1W ; expiry
1D ) ; minimum
IN NS dns.happy.com.
dns IN A 192.168.0.1
www IN A 192.168.0.1
~
有什麼不對嗎？！！！

你確定沒有修改任何地方條件下,出那錯是吧,
那麼
你第三次是什麼結果????
《解決方案》
我只要在/etc/reslou.conf中加上：
nameserver 127.0.0.1
就又會可以反向解析了，但是一會兒又不對了！還是方向解析成
Non-authoritative answer:
Name: DELL.mshome.net
Address: 192.168.0.1
用nslookup測試，就是：
# nslookup
> set type=SOA
> happy.com
;; connection timed out; no servers could be reached
# nslookup
> www.happy.com
;; connection timed out; no servers could be reached
# nslookup
> 192.168.0.1
Server: 192.168.0.1
Address: 192.168.0.1#53
Non-authoritative answer:
1.0.168.192.in-addr.arpa name = DELL.mshome.net.
很奇怪！我的windows的防火牆已經關了
我的主機的IP：192.168.0.1
我的VM虛擬機的IP：192.168.0.99
為什麼會有這樣的怪問題呢？
《解決方案》
這樣吧,你試著解析一下,不做任何修改
再看日誌 /etc/log/message
《解決方案》
我用natstat命令看了一下，這裡的domain怎麼不對啊？應該是192.169.0.1啊？怎麼該啊？
