If you know the IP address, just ping it straight away.
Go to Start, Run, and type in cmd.
Type in ping xxx.xxx.xxx.xxx (IP address). If it has lesser than 3
digits, don't need to add 0 in front. Just write it as it is. Like
1.2.3.4
If you don't know, type in ping www.thewebsite.com (replaced
thewebsite.com with the correct website)
