Understanding Outside DNS can be very complicated if you do not have a good understanding of it. Basically outside dns works in reverse of the way you would read it.

Let’s take the domain www.zwiegnet.com for example

when you type in www.zwiegnet.com it actually figures it out .com, then zwiegnet, then www

1).com will query the main Root Servers in the country and find out where the domain is registered (.com part)

2)from there it will determine where the domain resolves to (based on name server IP’s) (zwiegnet part)

3) the next step more than likely points to the hosting data center, so from there the www will point to what “host” or server in this case the website would be stored on.

www – Host/Server at datacenter

zwiegnet.com – Datacenter or group of datacenters domain is at

.com – the basis for all domains, will query for .com/.net/.org/.biz, so on
