Some advice as a Turkish citizen to friends who are new to censorship: never use the default ISP DSN. The simplest way of implementing government censorship is via DNS.
Ok so I'm an absolute novice at this stuff, but basically DNS tells your computer where on the Internet a particular website is located. Its IP address. Your router will likely default to the DNS server your ISP provides. My router, and I would guess most others, allows one to change which DNS server their computer uses. There is a list of DNS servers one can use, and among them is OpenDNS, owned by Cisco. Provided the Jem'Hadar don't attack, I should be good.
I'm reaching the end of my knowledge here, hope that summary helped
Yeah. I like to consider DNS the phone book of the internet. You know you want to talk to Google but you only know Google by name. Not their actual phone number. So your DNS server converts Google.com into 8.8.8.8 or whatever googles IP address is for you. What’s nifty is this can be used in a few ways to block/disallow certain content. And can slightly dictate the paths your connection takes on the internet.
