How to change localhost to www.dev.com on this machine

After installing the server on Windows, open the local directory C:\Windows\System32\drivers\etc\ , you will see a Hosts file, open after the code is:

# Copyright (c)1993- theMicrosoft corp.## This isA sample HOSTS file used by Microsoft TCP/IP forwindows.## This file contains the mappings for IP addresses to host names. each# entry should is kept on a individual line. The IP address should# be placedinchThe first column followed by the corresponding host name.# the IP address and the host name should is separated by at Least one# space.## Additionally, comments (such asthese) May is inserted on individual# lines or following the machine name denoted by a'#'symbol.## for example:##102.54.94.97rhino.acme.com # source server#38.25.63.10x.acme.com # x client host# localhost name resolution ishandled within DNS itself.#127.0.0.1localhost#::1localhost

At the bottom of this we add

     127.0. 0.1       Www.dev.com

Note that at this time can not have a semicolon, so that when we visit www.dev.com, in fact, the open is localhost, even if the line already has www.dev.com this domain name, open is also host on 127.0.0.1 this host.
