What Is Facebook’s IP Address? – Lifewire

Block Facebook’s IP address in addition to its domain name to restrict access to the social networking giant on your home network. Like many popular websites, Facebook uses many internet servers to handle incoming requests to its service, so to block Facebook, block the complete list of IP addresses that the company owns.
There is no direct method to find the IP address of a Facebook user.

Block Facebook Access
If you want to block access to Facebook from your home network, restrict these entire IP ranges:
66. 220. 144. 0 – 66. 159. 25569. 63. 176. 0 – 69. 191. 255204. 15. 20. 0 – 204. 23. 255
uses some but not all of the addresses in these ranges.
Reach Facebook by IP Address
Below are some of the most common active IP addresses for
69. 1369. 181. 1569. 184. 14269. 187. 1769. 1869. 1969. 1169. 12
In some cases, you can access Facebook by using an IP address instead of its usual URL. This shortcut is handy if you want to visit the social networking service but you cannot resolve domain names behind a given network.
IP address ownership can change. If you want to know if Facebook owns a specific IP address, go to the Whois website and copy the IP address into the search bar. The resulting information tells you who owns the IP address.
Check out tutorials about configuring your router’s built-in firewall or for using the Windows 10 firewall, if you need a refresher.

List of IP Space used by Facebook [closed] - Stack Overflow

List of IP Space used by Facebook [closed] – Stack Overflow

I am looking for an authoritative list of IP space Facebook uses. I need this to support a locked down developer environment that has very tight restrictions on outbound connectivity.
Today I found api and started resolving to 69. 171. 224. 0/19 which was not previously in my filters. I’ve updated it but I’d like to know what other IP space I’m missing allow rules for.
Here’s what I have currently. Any additional IP blocks you can list out would be great. Thanks everyone.
69. 63. 176. 0/20
69. 0/19
66. 220. 144. 0/20
204. 15. 20. 0/22

whois -h — ‘-i origin AS32934’ | grep ^route
