Hostname to IP lookup

[mtran]

Hi,

I see that there're many sites provides hostname to IP lookup. My question is, how do we know if the ip generated is for the main webhosting company (like Godaddy) or it's the (fixed) ip for that specific domain name? Very novice in IP and domain stuff. Thanks for the input!

It is for the specific domain name where is hosted the website

not always. there are more computers connected to the internet than there are IP addresses to label them with. often, a dedicated IP address costs extra. shared hosting plans are "shared": several sites on one machine, using one (or more) IP addresses (or even a dynamic IP address).
