puting, a hosts file, stored on puters filesystem, is used to look up the Internet Protocol address of a device connected to puter network, such as your puter connected to the Internet. The hosts file describes a many-to-one mapping of device names to IP addresses. When accessing a device by name, the networking system will attempt to locate the name within the hosts file if it exists.

Typically, this is used as a first means of locating the address of a system, before accessing the Internet domain name system. The reason for this is that the hosts file is stored on puter itself and does not require any network access to be used, whereas DNS requires access to an external system, which is typically slower.

In the earliest days of the Internets predecessor, ARPANET, there was no Domain Name System for resolving names into IP addresses. In order to simplify having to memorize IP addresses, a mechanism for translating memorable names to a valid IP address was developed.

This mechanism was the HOSTS file method. The TCPIP stack of an operating system would be modified so it would look up names from a file in order to try and translate them into IP addresses.

This method of performing name-to-IP lookups was in use for many years, as ARPANET was quite small and it was relatively easy to maintain a central HOSTS file that would be distributed to different sites. However, as ARPANET grew in size plexity and more sites started expanding their own local TCPIP networks the beginning of Intranets, the HOSTS method on its own became insufficient.

Thus the drive to develop a more scalable, dynamic system was started, which eventually resulted in the development of the widely-used DNS system. However, TCPIP-enabled operating systems from the ARPANET days in other words, Unix and its progeny retained the HOSTS mechanism up until the present day.

Other non-Unix operating systems such as Microsoft Windows also adopted the mechanism. In small networks, it still provides a simple and very fast way to do name-to-IP-address translation.

Since the late 1990s, the HOSTS file mechanism has been adopted primarily by Microsoft Windows as a way to protect puter systems from malware. At odds with the original intent of the HOSTS file, this adopted use actually takes host names that are perceived as malicious or unwanted and overlays them with safe IP addresses.

The hosts file is generally named hosts and is located in the following directories for each operating system: One use of the hosts file is ad filtering. This is plished by adding a line to the file that maps an ad servers hostname to an address that will not satisfy the browsers request for the ad.

Since no additional programs are necessary to do this, hosts file based ad-blocking has a near-zero memory and CPU footprint, as well as requiring no loading time. The hostname for an advertiser may be obtained by right-clicking on the banner or advertisement, then clicking properties from the context menu.
