manfightdragon shared a way to increase your PlayStation 4 download speed from 5 to 10 times faster by simply blocking some IP addresses in your router and rebooting your PS4 a few times with a PSN demo video below!
To quote from Kotaku who also confirmed this tweak: "After running some tests, he found that his PS4's were downloading from some foreign servers.
So to speed up the process, he set a firewall rule on the router and blocked them.
And as it turns out, the trick works. After blocking the servers, McDonald found his PS4s were finally downloading at the kinds of speeds his internet was more accustomed to delivering.
We tested the trick out in the Allure Media offices, where we have the luxury of a fat fibre pipe. When we began testing over Wi-Fi, the best download speeds we could achieve were around 18mbps. When connected via an ethernet cable that speed improved to just around 33mbps, which was better but still pretty substandard for 2017.
When we blocked the IP address Lance used, well... things improved a tad.
I wish I could download all of Destiny in an hour flat. (Before we blocked the IP, it would have taken several hours.) One thing to remember though: if you want to play games online, you'll have to re-whitelist the IP. According to McDonald, the server was necessary for online play and it also hosts a lot of assets on the PSN store. Better to be safe than sorry."
