I've been busy with creating my website when I found the plugin Jetpack by WordPress.com, but when I tried to connect to wordpress.com I got the "socket error: 111".
After a bit of searching I found out that it had to do with including external http ( correct me if I'm wrong ), and that it might be a problem with the server.
Again after a bit of searching I found out my server blocks most of the external http includes. I send a ticket to them asking if they could allow the plugin to their whitelist, and I received a positive reaction, but they need the IP-adresses that wordpress uses for this plugin.
Can anyone help me with this? I got no experience nor knowledge how to find this information.
