Hostname is the same as computer name. Sometimes its call machine name. Here is how to find your computer name in Windows and Mac:

Or you can type "hostname" at the command prompt

"Nameserver" is a DNS server -- this is where hostnames are associated with IP addresses. For example: In the context of web hosting, a nameserver points to a DNS server that serves a specific domain. In other words, the hostnames listed in a nameserver are other DNS servers, and the hostnames listed in the DNS server are your domain names

Nameservers require Glue Records, while a hostname can simply rely on A records.

I don't understand this

Normally I set hostname that associate with my IP address as follows

hostname --> IP address

and I need to setup reverse DNS too.

IP address resolve to my domain

while nameservers are

ns1.mydomain.com --- A --> IP address
ns2.mydomain.com --- A --> IP address

That is correct. ns1.mydomain.com is a hostname. The server that contains the file with all your hostname -- > IP entries (known as a zone file) is a nameserver, aka DNS server

Don't worry about that until you understand the other stuff

Hostname is the name of the server. It has a A record on the server itself. It is configured in /etc/sysconfig/network file. Like In a tv show a host who control the TV show and he explain everything. He has a name.

So just like that hostname on of the system is their. Nameserver are used to point the domain names towards a server. like : ns1.domain.com and ns2.domain.com nameserver can be private as well. hostname cant be private. Its assigned by the admin of the server.

What is the difference between hostname and nameserver?
