Facebook API communication IP address and Port number

I have a website that has strict filters to allow any communication with other websites such as Facebook. Can 开发者_运维百科anyone tell me what is the IP address and Port numbers for facebook REST and Graph APIs so that they can be allowed in my server..

They should allow by DNS not by IP. Facebook has something like 40,000 servers.

You'd want to allow

• *.facebook.com
• Ports 80 and 443

You better go to http://bgp.he.net/AS32934#_prefixes and got the total prefix of facebook.
