How can a server know exactly what domain name they were accessed from or if they were accessed directly through IP?

To me, dns was just words->IP and then the computer connects using the IP so how would the server know what domain name was used

They don't know unless the DNS server tells them. For example, a very popular webhost Akamai uses a complex DNS + web hosting suite (DNS edgesuit to be exact) to send that type of data to the web servers. It can also allow for many many other features.
