使用 DNS 服务器如何影响我所处的位置

How can using a DNS server influence where I am perceived to be located

此博客 post ("How to Easily Watch Netflix and Hulu From Anywhere in the World") 解释了美国以外的人如何通过更改 DNS 服务器来观看 Netflix 和 Hulu(通常仅限于居住在美国境内的人)。

我的问题是,这会如何改变 Hulu 查看您的位置的方式? 据我了解,DNS 服务器只是为您将网址转换为 IP 地址。但是,归根结底,它仍然是 您的 计算机连接到网站,比方说 Hulu。 Hulu 仍然知道我的电脑不在美国。 Hulu 不知道我是如何得到它的地址的(即他们不关心哪个 DNS 服务器告诉我)

您在这里唯一需要知道的是这些是 tunlr DNS 服务 IP。这里的技巧是通过 tunlr 路由所有流量,这使您能够使用虚拟位置而不是更传统的 VPN 或代理。

来自他们的常见问题解答:

Tunlr does not provide a virtual private network (VPN). Tunlr is a DNS (domain name system) unblocking service. We’re using sophisticated technologies (a.k.a. the Tunlr Secret Sauce ©) to re-adress certain data envelopes, tricking the receiver into thinking the envelope originated from within the U.S. For these data envelopes, Tunlr is transparently creating a network tunnel from your location to our U.S.-based servers. Any data that’s not directly related to the video or music content providers which Tunlr supports is not only left untouched, it’s also not even routed through Tunlr. In order to use Tunlr, you will have to change the DNS address. See Get started for more information.
