求教高手帮我看看 dns问题。 环境是RHEL 4 系统带的bind 。
C:\Documents and Settings\Daniel>nslookup
Default Server: dns.shdmt.net.159.168.192.in-addr.arpa
Address: 192.168.159.237
> 192.168.159.237
Server: dns.shdmt.net.159.168.192.in-addr.arpa
Address: 192.168.159.237
我想ip对应的应该是dns.shdmt.net， 怎么结果解析出来这么长呢，不知道是不是正常？
以下是我的配置
zone "." IN {
type hint;
file "named.ca";
};
zone "localhost" IN {
type master;
file "localhost.zone";
allow-update { none; };
};
zone "0.0.127.in-addr.arpa" IN {
type master;
file "named.local";
allow-update { none; };
};
zone "shdmt.net" IN {
type master;
file"shdmt.zone";
};
zone "159.168.192.in-addr.arpa" IN {
type master;
file "shdmt.local";
};
include "/etc/rndc.key";
反向解析 shdmt.local内容
@ IN SOA dns.shdmt.net root.dns(
20080219 ;serial
28800 ;refresh
7200 ;retry
604800 ;expire
86400 ;minimum
)
@ IN NS dns.shdmt.net
237 IN PTR dns.shdmt.net
日志是：
