Host Name or Domain Name

A domain name is the name that is purchased from a registrar. It will be something like or Note that there is no www at the beginning of a domain name. A domain name can be subdivided into sub-domains - for example Once you own a domain, there is no reasonable limit to the number (or names) of the sub-domains you can create. A sub-domain can be allocated to a host machine - for example a PC. In fact many sub-domains can be allocated to the same host machine. The way sub-domains are allocated to a host machine is to create a record in the DNS (Domain Name Servers) that records the sub-domain name and the IP address of the host machine. Any requests for a sub-domain (e.g. are converted to an IP address by DNS and the IP address is used to route the request through the network until it reaches the host machine.

In the early years of the Internet, each sub-domain would have a unique IP address so it was common for a host machine to have only one sub domain name. Nowadays, the common practice is to have many sub-domains with the same IP address. It is also common for the domain name to be converted to the IP address of the host machine that runs the www sub domain.

A host name is the unique name of a machine. When the host operating system is set up it is given a name. This name may reflect the prime use of the machine. For example, a host machine that converts host names to IP addresses using DNS may be called and a host machine that is a web server may be called When we need to find the host name from an IP address we send a request to the host using its IP address. The host will respond with its host name.


What is an IP address?

Today, no one can deny the importance of the internet. In reality, we are living in the era of the internet. Somehow, we are connected to the internet through our digital devices. And perform various activities around the clock.

Each device connected to the internet has a unique numeric identifier, called an IP address. In general, the IP address means the Internet protocol address. Internet protocol is the guidelines or rules and regulations that ensure and regulate internet connectivity.

Digital devices understand the numeric language. The IP address (Internet Protocol Address) is a unique numeric string identifier. It is separated by periods and is allocated to each device, including computers, tablets, mobiles, or any other digital device part of the TCP/IP-based network. Without the IP address, you cannot connect to the internet. You can check your device with the check my IP tool.

Mostly, people do not give much weight to an IP address. But you can get information about its user from an IP address. You can even get the user's location by tracking the IP address's exact location.
