Hosts Windows

In this post we will see about hosts windows. The hosts file is a Windows system file that can override DNS and redirect URLs or IP addresses to different locations. The hosts file is used by operating systems to map human-friendly hostnames to numerical Internet Protocol (IP) addresses that identify and locate a host in an IP network. The hosts file is one of several system resources that address network nodes in computer networks and is a common part of an operating system’s IP implementation. The computer file hosts is an operating system file that maps hostnames to IP addresses. A file originally named HOSTS.TXT was manually maintained and made available via file sharing by the Stanford Research Institute for ARPANET subscriptions, with hostnames and host names for inclusion by member organizations. Addresses included.

What is the Hosts File in Windows?

The hosts file also known as hosts is a text file used by Windows to map IP addresses to host names or domain names. The hosts file contains lines of text in which one or more host names in the first text field is followed by the IP address. Each field is separated by white space. Comment lines may be included, and they are indicated by the hash character (#) at the first position of such lines. Completely blank lines in the file are ignored. you will need to edit the hosts file on your machine. Sometimes because of an attack or prank, and others so that you can simply and freely control access to websites and network traffic. hosts files have been in use since ARPANET. They were used to resolve hosts names before DNS. hosts files would be massive documents used to aide the network name resolution.
