Wildcards in a Windows hosts file

Question

I want to setup my local development machine so that any requests for   local are redirected to localhost  The idea is that as I develop multiple sites  I can just add vhosts to Apache called site1 local  site2 local etc  and have them all resolve to localhost  while Apache serves a different site accordingly   I am on Windows XP   I tried adding   127 0 0 1         local   to my c  windows system32 drivers etc hosts file  also tried   127 0 0 1        local   Neither of which seem to work   I know I can set them up on different port numbers  but that is a pain since it is hard to remember which port is which   I don t want to have to setup a local DNS server or anything hard  any suggestions

To add to the great suggestions already here, XIP.IO is a fantastic wildcard DNS server that's publicly available.

      myproject.127.0.0.1.xip.io  -- resolves to -->   127.0.0.1
  other.project.127.0.0.1.xip.io  -- resolves to -->   127.0.0.1
   other.machine.10.0.0.1.xip.io  -- resolves to -->   10.0.0.1

(The ability to specify non-loopback addresses is fantastic for testing sites on iOS devices where you cannot access a hosts file.)

If you combine this with some of the Apache configuration mentioned in other answers, you can potentially add VirtualHosts with zero setup.

I m using DNSChef to do that   https   thesprawl org projects dnschef   You have to download the app  in Linux or Mac you need python to run it  Windows have their own exe   You must create a ini file with your dns entries  for example    A    google com 192 0 2 1   local 127 0 0 1   devServer1 com 192 0 2 3   Then you must launch the dns application with admin privileges  sudo python dnschef py --file myfile ini -q   or in windows  runas dnschef exe --file myfile ini -q   Finally you need to setup as your only DNS your local host environment  network  interface  dns or similar or in linux  etc resolv conf    That s it

Editing the hosts file is less of a pain when you run  ipconfig  flushdns  from the windows command prompt  instead of restarting your computer

petah and Acrylic DNS Proxy is the best answer  and at the end he references the ability to do multi-site using an Apache which  jeremyasnyder describes a little further down         however  in our case we re testing a multi-tenant hosting system and so most domains we want to test go to the same virtualhost  while a couple others are directed elsewhere   So in our case  you simply use regex wildcards in the ServerAlias directive  like so     ServerAlias   foo local

You can use a dynamic DNS client such as http   www no-ip com  Then  with an external DNS server CNAME   mydomain com to mydomain no-ip com

You can use echoipdns for this  https   github com zapty echoipdns      By running echoipdns local  all requests for  local subdomains are redirected to 127 0 0 1  so any domain with xyz local etc will resolve to 127 0 0 1  You can use any other suffix also just replace local with name you want   Echoipdns is even more powerful  when you want to use your url from other machines in network you can still use it with zero configuration    For e g  If  your machine ip address is 192 168 1 100 you could now use a domain name xyz 192-168-1-100 local which will always resolve to 192 168 1 100  This magic is done by the echoipdns by looking at the ip address in the second part of the domain name and returning the same ip address on DNS query  You will have to run the echoipdns on the machine from which you want to access the remote system   echoipdns also can be setup as a standalone DNS proxy  so by just point to this DNS  you can now use all the above benefits without running a special command every time  and you can even use it from mobile devices   So essentially this simplifies the wildcard domain based DNS development for local as well as team environment   echoipdns works on Mac  Linux and Windows   NOTE  I am author for echoipdns

I could not find a prohibition in writing  but by convention  the Windows hosts file closely follows the UNIX hosts file  and you cannot put wildcard hostname references into that file   If you read the man page  it says   DESCRIPTION      The hosts file contains information regarding the known hosts on the net-      work   For each host a single line should be present with the following      information              Internet address            Official host name            Aliases   Although it does say        Host names may contain any printable character other than a field delim-      iter  newline  or comment character    that is not true from a practical level   Basically  the code that looks at the  etc hosts file does not support a wildcard entry   The workaround is to create all the entries in advance  maybe use a script to put a couple hundred entries at once

To answer your question  you cannot use wildcards in the hosts file under Windows   However  if you want to only change the hosts file to make new sites work     you can configure your Apache like this and you don t have to keep editing it s config   http   postpostmodern com instructional a-smarter-mamp   Basically a quick summary based on my setup  add the following to your apache conf file    LoadModule vhost alias module modules mod vhost alias so   NameVirtualHost   80     lt Directory   xampp sites  gt        Options Indexes FollowSymLinks Includes ExecCGI       AllowOverride All       Order allow deny       Allow from all     lt  Directory gt      lt VirtualHost   80 gt        VirtualDocumentRoot c  xampp sites  -1  -2      lt  VirtualHost gt    This allows me to add an entry like   127 0 0 1       test dev   and then make the directory  c  xampp sites dev test and place the necessary files in there and it just works   The other option is to use  lt Directory gt  tags in apache conf and reference the pages from http   localhost project

I don t think that it is possible   You anyway have to modify the apache virtualroot entries every time you add a new site and location  so it s not a big work to syncronise the new name to the Windows vhost file   Update  please check the next answer and the comments on this answer  This answer is 6 years old and not correct anymore

We have this working using wildcard DNS in our local DNS server  add an A record something like   local - gt  127 0 0 1  I think that your network settings will need to have the chosen domain suffix in the domain suffix search list for machines on the network  so you might want to replace  local with your company s internal domain  e g   int  and then add a subdomain like  localhost int to make it clear what it s for   So   localhost int would resolve to 127 0 0 1 for everybody on the network  and config file settings for all developers would  just work  if endpoints hang off that subdomain e g  site1 localhost int  site2 localhost int This is pretty much the scheme we have introduced   dnsmasq also looks nice  but I have not tried it yet  http   ihaveabackup net 2012 06 28 using-wildcards-in-the-hosts-file

I found a posting about Using the Windows Hosts File that also says  No wildcards are allowed    In the past  I have just added the additional entries to the hosts file  because  as previously said   it s not that much extra work when you already are editing the apache config file

You could talk your network administrator into setting up a domain for you  say  evilpuppetmaster hell   and having the wildcard there so that everything    evilpuppetmaster hell   resolves to your IP

User · Answer

While you can t add a wildcard like that  you could add the full list of sites that you need  at least for testing  that works well enough for me  in your hosts file  you just add   127 0 0 1       site1 local 127 0 0 1       site2 local 127 0 0 1       site3 local
