the IP address for the 3.5.2 update

Does anyone know the IP address of the 3.5.2 update? I cannot auto-update, and cannot get the update to show by clicking “check again”. I’m stuck at 3.5.1 and DO NOT want to do a manual update. I saw that the themes (which I dont use) needed updated and once I went on my server and allowed the outgoing connection for the IP address of those updates, I was fine and dandy. However, I need the IP address of the 3.5.2 update if anyone can provide. (no help from my web host’s tech support)
