Fix nslookup works but ping fails in Windows 10/11

Imagine a situation where certain websites on your system aren’t working, however the Internet is connected (which is evident by other websites which are opening). The websites which are not working on your system could be working on other devices (eg. your phone). In this situation, it could be understood that the issue is with the system itself.

In such a situation, we could use two command line tools: ping and nslookup. We open the Command Prompt window after searching through Windows search and use these commands. Eg. ping <website name>, nslookup <website name>.

The ping command sends packets of information to the IP address or the domain and checks for replies. However, it does not lookup to the DNS, something which is done by the nslookup command.

If the ping command gives all 4 replies but nslookup gives the error “Could not find host,” this post could be of help to you.Nslookup Failed
