- Question
Due to our strict security policy, we block access from specific countries. Consequently, our Social Login application (https://developers.facebook.com/apps) is occasionally blocked as Facebook cannot reach our pages.
Is there a list of Facebook IPs available that we can use to create whitelist rules in our Web Application Firewalls (WAFs)?
Best Regards.
I've seen similar questions but no answers so far.
As of my last knowledge update in January 2022, Facebook's IP addresses can change frequently, and they typically use a Content Delivery Network (CDN) to distribute their content. This makes it challenging to maintain an up-to-date and accurate list of Facebook's IP addresses.
Instead of whitelisting specific IP addresses, Facebook recommends allowing access to their entire IP address range. They provide the Autonomous System Number (ASN) that represents their network. You can use the following ASN to create whitelist rules:
ASN: 32934
It's essential to regularly check for updates from Facebook or refer to their official documentation for any changes in their network infrastructure. Keep in mind that relying on IP whitelisting can have limitations, and it's always a good practice to implement additional security measures for your applications. source: https://hollybollyera.site/who-is-the-tallest-actress-in-bollywood/
