Nslookup to check whether the Changed dns record takes effect

Check whether the dns server change takes effect.
First, let's take a look at the domain name resolution sequence priority:
 
 
1. Local DNS Cache
2. Local Hosts file
3. DNS Server
 
 
View the local DNS Cache: ipconfig/displaydns
 
 
Clear local DNS Cache: ipconfig/flushdns
 
 
Hosts file location: C: \ WINDOWS \ system32 \ drivers \ etc
 
 
 
 
Run the nslookup command to check whether the DNS change takes effect.
 
 
 
 
Under DOS (Start Menu-run), enter nslookup
 
 
C: \ Users \ Administrator> nslookup
Default Server: google-public-dns-a.google.com
Address: 8.8.8.8
 
 
> Set type = ns
> Baidu.com
Google-public-dns-a.google.com Server
Address: 8.8.8.8
 
 
Non-authoritative response:
Baidu.com nameserver = ns4.baidu.com
Baidu.com nameserver = dns.baidu.com
Baidu.com nameserver = ns3.baidu.com
Baidu.com nameserver = ns2.baidu.com
