on my computer(windows 10), the dns server that ping.exe use is different from the dns server nslookup use. i set 192.168.123.1 to be my computer's dns server, which is my router. so nslookup uses it as the dns server:



PS C:Userspeter> nslookup.exe fm.zju.edu.cn
server: RT-N14U.lan
Address: 192.168.123.1

name: fm.zju.edu.cn
Address: 10.214.0.99


this ip address ic correct, which is school-internal ip.

but the ping result is different:



PS C:Userspeter> ipconfig.exe /flushdns

Windows IP Configuration

Successfully flushed the DNS Resolver Cache.
PS C:Userspeter> ping fm.zju.edu.cn

Pinging fm.zju.edu.cn [210.32.157.99] with 32 bytes of data:


then i use wireshark to find out that ping.exe send dns request to another dns server 114.114.114.114. i used to use this dns server, but i doesn't use it for about a month.

i reset the network settings, but the ping.exe still use 114.114.114.114 as its dns server.

i don't know how to solve this problem.

          change the mtu value of network card from 1500 to 1280 and many other things.
