Question

While troubleshooting a network connection problem for a coworker, you discover the computer is querying a nonexistent DNS server. What command line utility can you use to assign the correct DNS server IP address?

Answer 1

Answer:

nslookup ifconfig.

Explanation:

The nslookup is used a number of times by network admins to troubleshoot DNS related problems. In addition, this command finds IP addresses and name servers of hosts. This utility command queries the DNS database tables from every host in a network. It then determines the host name and issues an IP. It sort of converts your domain name into an IP addresses. This command combined with ifconfig finds the correct DNS servers and assigns the correct DNS server IP.
