如何在Windows上绕过主机文件获取真实IP地址

Question

I added a host-ip mapping in my C:\\Windows\\System32\\drivers\\etc\\hosts

192.168.1.105 www.facebook.com

I tried both getaddrinfo and DnsQuery, neither works.

The DsnQuery code is from this example . The result is:

The IP address of the host www.facebook.com is 192.168.1.105

However, the command 'nslookup' works fine:

C:\\Users\\abc>nslookup www.facebook.com

服务器: public1.114dns.com

Address: 114.114.114.114

非权威应答:

名称: www.facebook.com

Addresses: 200:2:2e52:ae44::

  93.46.8.89 

Answer 1

I thought DNS_QUERY_BYPASS_CACHE might do the job. But actually DNS_QUERY_NO_HOSTS_FILE should be used.
