  Added a new IP for our new Tokyo PoP.

  we have added APNIC range : 103.28.248.0/22

  Why not set up a page that is always up to date, where clients can cut-and-paste the exact information needed for the .htaccess file?

• 
  gregraven February 17, 2012 13:27

  For that matter, Incapsula already has a WordPress plug-in to sort out the IP confusion that happens with services such as this. Why not add a feature to this plug-in to write to .htaccess with the current whitelist?

  if you use nginx, make sure you have the realip module, and add this to nginx.conf :

   

          set_real_ip_from 199.83.128.0/21;
  
          set_real_ip_from 149.126.72.0/21;
  
          set_real_ip_from 103.28.248.0/22;
  
          set_real_ip_from 194.90.228.56/29;
  
          set_real_ip_from 46.51.174.78;
  
          set_real_ip_from 184.73.240.163;
  
          set_real_ip_from 122.248.247.129;
  
          set_real_ip_from 173.203.97.38;
  
          set_real_ip_from 79.125.118.62;
  
          set_real_ip_from 176.32.89.123;
  
          real_ip_header X-Forwarded-For;

  A major update:

  •  removed the 194.90.228.56/29 range

  • removed many of the single IPs (184.73.240.163, 173.203.97.38, 176.32.89.123)

  • Added additional IPs : 50.16.241.95, 50.16.241.176, 184.169.135.107, 184.169.135.111, 46.137.108.0, 46.51.168.190, 79.125.110.134

  Hi,

   Thanks for the update, it possible to be notified prior to these changes being implemented so we can schedule the change at our end without affecting access to our sites?

   Cheers!

  alex b May 03, 2012 11:53

  Hi, I second last comment. Can we get an early notification? we must notify our customers of the change as they restrict the destination IPs.

  Hi,

   

  Few updates:

  1. An additional range was added : 198.143.32.0/19  This range will become active on** June 1st. **(for those who requested early notification :))

  2. As several people have provided specific configurations for htaccess, nginx and iptables, I've incorporated them into the article and will keep them updated going forward. Thank you for all the contributors!!

   

  Have Fun.

  Warren Meyer July 25, 2012 06:30

  I am sorry if this is a staggeringly noob question, but if I lock down ht access to allow only traffic from incapsula, I presume this will block my ftp access to the site (unless I ftp from the same IP and whitelist that as well).  Correct?  Or is there a way to block http calls but not ftp?

• 
  Jitendra Dhamani July 25, 2012 06:37

  Websites: Port 80 Blocked after htaccess allow only traffic from incapsula,

  FTP: Port 20, 21 Accessible by everyone

  Hi to all followers :)

   

  Please note that we have added another range : 185.11.124.0/22

  Please make sure to update your firewall rules.

  zzzzzzz March 18, 2013 03:21

  We are using Dome9 with Incapsula and they have something called Magic-IP for Incapsula and it dynamically configures our servers to accept traffic only from Incapsula. They keep updating their Incapsula list when Incapsula changes, so we don't have to worry about it. and we use them to block phpmyadnin and ssh to our servers as well

• 
  uri March 20, 2013 11:57

  Hello all,

   

   

  We have decide to remove all the single IPs which were used by some of our old POPs.

  I have updated the list and the sample configurations accordingly. You can find it in the article at the top of the discussion thread.

  for your convenient, here is the complete list of IPs used by Incapsula's POPs:

  199.83.128.0/21
  
  198.143.32.0/19
  
  149.126.72.0/21
  
  103.28.248.0/22
  
  185.11.124.0/22

  Hi,

  I wish to suggest that this list of IP addresses will be stored in a fixed HTTPS (for validation) URL at the Incapsula site, as a structured file format, like CSV, XML, JSON or whatever, so clients will have the option to customize their back-end systems usage of this input, based on this list constantly and automatically, even if the list changes - not needing to relay on notifications from this thread and then manually adjust changes.

  Too hard to keep up with IP ranges - it's like another job.

• 
  Yoav1987 May 08, 2013 06:53

  Tips: don't forget to add the ip to all you .htaccess (root, forum, other folders).

  #Incapsula

  order deny,allow
  
  deny from all
  
  allow from  199.83.128.0/21
  
  allow from  198.143.32.0/19
  
  allow from  149.126.72.0/21
  
  allow from  103.28.248.0/22
  
  allow from  185.11.124.0/22

  If you are behind a proxy or load-balancer and use Apache, the aforementioned code won't work since you need to look for the X-FORWARDED-FOR HTTP header instead of the actual IP address originating the connection. In that case, you could use mod_rewrite like so:

  Turn on rewrite engine, only needed once

  RewriteEngine On

  Limit IP addresses to those from Incapsula

  --> http://support.incapsula.com/entries/20199668-Restricting-direct-access-to-your-website-Incapsula-s-IP-addresses-

  199.83.128.1 - 199.83.135.254

  RewriteCond %{HTTP:X-Forwarded-For} !199.83.1(2[89]|3[0-5]).[0-9]{1,3}$

  198.143.32.1 - 198.143.63.254

  RewriteCond %{HTTP:X-Forwarded-For} !198.143.(3[2-9]|[45][0-9]|6[0-3]).[0-9]{1,3}$

  149.126.72.1 - 149.126.79.254

  RewriteCond %{HTTP:X-Forwarded-For} !149.126.7[2-9].[0-9]{1,3}$

  103.28.248.1 - 103.28.251.254

  RewriteCond %{HTTP:X-Forwarded-For} !103.28.2(4[89]|5[01]).[0-9]{1,3}$

  185.11.124.1 - 185.11.127.254

  RewriteCond %{HTTP:X-Forwarded-For} !185.11.12[4-7].[0-9]{1,3}$

  Fail

  RewriteRule .* - [L,F]

   

  Ideally you should still add client IP restrictions to ensure the connections are all originating from the expected proxy/load balancer as well, since X-FORWARDED-FOR headers can be spoofed by a malicious client that is able to connect directly to the web server.

  how do I do with iis 7.5 of window 2008 r2 standard 64bit server ,

  Thanks,

  Mat Timpug August 31, 2013 07:30

  Hopefully you guys do something like the cloudflare did at https://www.cloudflare.com/ips-v4 so we can set up a cron job or something that will fetch the ip lists automatically for whitelist.

• 
  Samuel Aguilera September 26, 2013 00:32

  Maybe this list is getting obsolete?

  I'm receiving visits to my site from 198.143.38.* and 198.143.39.* ranges not listed in the above list.

  It would be a very handy resource to have something like proposed by min0taur.

• 
  zzzzzzz September 26, 2013 05:15

  wphost  - I agree with you. how are you restricting the access to your server today?

   

• 
  Rod September 26, 2013 05:52

  wphost,

  I was going to wait for support to respond to you, but the last comment has prompted me to go ahead and chime in.  

  I am a customer and I am subscribed to this page to monitor changes.  While this is not automated to update my firewall rules, the changes seem to be infrequent, and I get an email about any changes or posts to this page.  There is a subscribe link at the top right of the page. 

  The ranges stated above include 198.143.32.0/19 which is a superset of the ranges that you mention (198.143.38.* and 198.143.39.* )

  198.143.32.0/19  includes all IPs between 198.143.32.1 - 198.143.63.254 (32 Class C networks)

  Another way to state it is 198.143.32.0 with a netmask of 255.255.224.0 .

  You should make sure that you have the netmask correct in your rules.

  I hope this helps.

  Rod

  Just note that there is no need for you to manually track this page and update all your servers if you use dome9.com. There is a Magic IP for Incapsula (as well as for CloudFlare) that will push the relevant configuration to your iptables or Windows firewall.
