A 'Domain name' is purchased from a registrar such as Easily.co.uk; it is a label that identifies the control and autonomy on the Internet based on the 'Domain Name System' (DNS). These are usually given as: .gov, .edu, .com, .net, .org, .mil etc. (E.g. education.com which comes without www). They identify one or more IP addresses. DNS also include sub domains that do not have any name and a domain can have innumerable sub domains. (www.education.com) Sub domains are allocated to the same host name that is recorded in the DNS, which also includes IP addresses of the host machine. Usually sub domains hold the same IP address.
The IP address or the 'Internet Protocol' address is a numeric label (32 bit numeric address written as a set of 4 numbers separated by periods, numbers ranging from zero to 255), which distinguishes a computer on the TCP/IP network (TCP - Transmission Control Protocol). The computer administrator assigns static IP addresses manually. The computer interface or the host software assigns dynamic IP addresses. All of these are usually allocated through regional organizations, thereby helping in the identification of the country in which the IP address resides.
Host domain name or 'hostname' is usually a string of alphanumeric c
haracters and means a 'Fully Qualified Domain Name' (FQDN), which can be identified (uniquely and absolutely) by naming a computer that is toggled to the internet via the domain name service identification hierarchy. FQDN refers to the name of the host, a period and the domain name. Periods (a dot) separate the host and domain name.
A request for a sub domain is routed to the network by converting it to the IP address by DNS, thereby reaching the host machine. A host name can be found by a request that is routed to the host using its IP address. Computers can host many domains; hence the host name can be the domain hosted or any other name. These names can also be converted to an IP address of the host machine that manages the www sub domain. Similarly, a name can be found by routing a message to the IP address requesting it to return its name. DNS lookup (also called NS lookup or IP lookup) is the process of finding IP addresses by conducting a search on the DNS servers. Usually every computer has a name of 'localhost' and holds the IP address of 127.0.0.1 (though a computer can have one or more IP addresses which is used to connect with other computers).
In short, host names are the folio markers in the DNS. Host domain names include DNS domains together with IP addresses of the host they symbolize and map the host name to an IP address or vice-versa.
