Does every domain have unique IPs?

Question

I want to know whether every domain adress has a unique IP adress? Furthermore, where these IP\'s are located? and how does this redirection system works? When we try to access

Answer 1

No, each domain doesn't need to have its own allocated IP address. IPs can be physically located anywhere. Redirection is usually done via user agents following HTTP instructions.
