There are many different methods for determining network capabilities in NCSI, one of which is determining the ability to access the Internet. The check is carried out in two stages:
• When connected to the network, the system sends an HTTP request to www.msftncsi.com/ncsi.txt. This is a plain text file containing just one line of Microsoft NCSI. In case of a successful request, the server should return a response with a 200 OK header containing this line;
• The second step checks that the DNS service is up and running by trying to resolve the dns.msftncsi.com name to the IP address. Expected value 131.107.255.255

but in general yes - google yourself will be faster
