I'm setting up a remote Apache webserver from scratch and I'm a bit confused about what role DNS plays on a webserver. I have a rudimentary understanding of how the DNS system works but I must be confused somewhere along the line.
1. On my PC I believe that the DNS settings I enter when I setup my broadband service tell my PC where to go to resolve domain names. Is this correct?
2. When I setup a URL it has a DNS control panel where I can set up my name servers and A/C/MX records. This server then communicates with the "Big 14" and tells them where my domain is located. Eventually my ISP's name servers get the info and when I type the url into my browser my PC goes to my allocated name servers and resolves the IP. Is this correct?
3. What does the DNS on an apache webserver do? Is it replacing the one described above (ie 2) or is it working like the PC DNS settings described above (ie 1) or is it doing something else?
