nslookup -qe=mx ebadu.net
邪确 批示:
C:\Documents and Settings\Administrator>nslookup -qe=mx ebadu.net
Server: ns.ahhfptt.net.cn
Address:  二0 二. 一0 二. 一 九 二. 六 八
DNS request timed out.
timeout was  二 seconds.
Non-authoritative answer:
ebadu.net MX preference = 0, mail exchanger = mail.ebadu.net
ebadu.net nameserver = ns 二.dns.com.cn
ebadu.net nameserver = ns 一.dns.com.cn
mail.ebadu.net internet address =  二 二 二. 一 八 六. 一 二. 一 六
ns 一.dns.com.cn internet address =  一 二 二. 七0. 一 三 八. 五
ns 一.dns.com.cn internet address =  一 二 二. 七0. 一 三 八. 六
ns 一.dns.com.cn internet address =  一 二 四. 四 二. 一 二 二. 八
ns 一.dns.com.cn internet address =  一 二 四. 四 二. 一 二 二. 九
ns 二.dns.com.cn internet address =  一 二 四. 四 二. 一 二 二. 五
ns 二.dns.com.cn internet address =  一 二 四. 四 二. 一 二 二. 六
ns 二.dns.com.cn internet address =  一 二 二. 七0. 一 三 八. 八
ns 二.dns.com.cn internet address =  一 二 二. 七0. 一 三 八. 九

睹到NS记载 隐示了IP 即为通行 状况

nslookup -qe=mx ebadu.com

C:\Documents and Settings\Administrator>nslookup -qe=mx ebadu.com
Server: ns.ahhfptt.net.cn
Address:  二0 二. 一0 二. 一 九 二. 六 八
DNS request timed out.
timeout was  二 seconds.
Non-authoritative answer:
ebadu.com canonical name = www.center.ebadu.net
ebadu.net
primary name server = ns 二.dns.com.cn
responsible mail addr = root.ns 二.dns.com.cn
serial =  二00 八0 六 一 一 一 三
refresh =  三 六00 ( 一 hour)
retry =  三 六00 ( 一 hour)
expire =  六 八 四00 ( 一 九 hours)
default TTL =  一 八0 ( 三 mins)
反馈没有归NSIP记载 .即为欠亨 状况 !
检测反解析是可胜利
nslookup –qt=ptr  六 一. 一 九 一. 一 九 一. 一 八 二

回归疑息以下：
C:\Documents and Settings\user>nslookup –qt=ptr  六 一. 一 九 二. 五 六. 二 三
Server: mx.diyway.net
Address:  六 一. 一 九 二. 五 六. 二 三
解释 那个IP的反解析便是胜利 了。

回归疑息以下
C:\Documents and Settings\user>nslookup –qt=ptr  六 一. 一 九 二. 五 六. 二 三
奸淫Can 三 九;t find server name for address  六 一. 一 四 二. 八0. 一 五 四: Non-existent domain
Server: UnKnown
Address:  六 一. 一 九 二. 五 六. 二 三
解释 那个IP的反解析出有做。
