The simplest way to find the IP address for a particular hostname is with the ping command. In Windows, open a command prompt as follows:
- Click on the Start menu
- Click Run...
- Type cmd then click on the OK button.
- Type ping domainname.com. Replace "domainname.com" with your actual domain name.
- You should get an output that looks like this:
Pinging dns1.speedingbits.com [18.104.22.168] with 32 bytes of data:
Reply from 22.214.171.124: bytes=32 time=1ms TTL=64 (et cetera).
In this case, the IP address is 126.96.36.199, though yours will be different.
To ping in the Mac OS X Environment:
Double-click on the Hard Drive icon > Applications folder > Utilities folder > Network Utility program
