Imagine that you are trying to visit www.enterprise, but you don't remember the IP address the web-server is running on. What can you do to find the IP address?
1) Use the 'ping' command to send a request to the domain name and get the IP address
2) Use the 'nslookup' command to query the DNS server and get the IP address
3) Check the website's contact page for the IP address
4) Try different IP addresses randomly until you find the correct one
