IP Whitelists for Salesforce 

My friends, I recently had a little run in with the Salesforce IP Whitelist range. Allow me to explain.

I have recently been putting the finishing touches on a web-service that I've been putting together as a side project. This morning, I was planning to configure the whitelist to only accept incoming calls from Salesforce. I was logged into my Microsoft IIS account working on the project, and I just had to find the Salesforce network IP addresses that I wanted to whitelist.

I did a quick search: nothing. I was a little taken aback. This was extremely useful information that was proving increasingly difficult to find. It ended up taking me over 25 minutes to sift through search results on Salesforce.com to finally find the IP whitelist range.

As most of you know, IP whitelists are phenomenal for restricting access to a select group of IP addresses for a given server. This is a great security measure to implement in any scenario where you know you want to limit the group of people that can visit your site. In my case, I knew that I would eventually be connecting this web-service to my billing account when I put it on the market, so I wanted to be sure all of the information was secure. That meant restricting access to Salesforce.com users.

I've copied out the official Salesforce.com IP Address Range to Whitelist below in order to make sure that nobody has to waste time searching for it again.

The IP address spaces are as follows:

204.14.232.0/23 East Coast Data Center (set one)
204.14.237.0/24 East Coast Data Center (set two)
96.43.144.0/22  MidWest Data Centers
96.43.148.0/22  MidWest Data Centers
204.14.234.0/23 West Coast Data Center (set one)
204.14.238.0/23 West Coast Data Center (set two)
202.129.242.0/23 Singapore Data Center
182.50.76.0/22 Japan Data Center

 

Need help with the CIDR subnet notation? Here is a greate website I found that explains it.

Here is the link to the official Salesforce.com IP Address Range to Whitelist. Happy whitelisting!

My question those IP addresses needs to be added on the salesforce side or on the server hosting webservice.

Thanks
