Google is blocked in some countries. However, there are many ways to access Google, like VPN, agent, and by changing the hosts file.

nslookup google.com is the easiest way. Works on Linux and Windows.
If your issue is that your DNS server is not returning a response for google.com, use a different DNS server, such as a public one. For instance, you could do:
nslookup
>server 8.8.8.8
>google.com
