请教網中人\阿骁:wal-mart.com有无问题?
我用 host 來查的結果:
- [netman@www netman]$ host -t ns shenzhougroup.com
- shenzhougroup.com name server ns2.dns-diy.com.
- shenzhougroup.com name server ns1.dns-diy.com.
- [netman@www netman]$ host ns2.dns-diy.com
- ns2.dns-diy.com has address 218.85.134.143
- ns2.dns-diy.com has address 218.107.207.123
- [netman@www netman]$ host ns1.dns-diy.com
- ns1.dns-diy.com has address 210.51.187.81
- [netman@www netman]$ host -t ns shenzhougroup.com ns2.dns-diy.com
- Using domain server:
- Name: ns2.dns-diy.com
- Address: 218.85.134.143#53
- Aliases:
- [netman@www netman]$ host -t ns shenzhougroup.com ns1.dns-diy.com
- ;; connection timed out; no servers could be reached

改用 dig 則是:
- [netman@www netman]$ dig ns shenzhougroup.com
- ; <<>;>; DiG 9.2.1 <<>;>; ns shenzhougroup.com
