在这个时代，谁还在使用普通的互联网连接？你做？好吧(Well)，不要为此感到难过。在修改互联网连接以获得更好的安全性、隐私或扩展功能时，大多数人都没有意识到他们的选择。
但是，如果您确实想隐藏您的互联网活动或对锁定的内容执行地理解锁，那么提供的一些选项可能会让所有新手感到有些困惑。像“VPN”和“Smart DNS”这样的术语被同性恋抛弃了。
这些技术有一些表面上的相似之处，但以根本不同的方式工作。如果您最终使用了错误的技术来满足您的需求，可能会产生一些严重的后果。因此，让我们揭开这些首字母缩略词的神秘面纱，并解决您可能存在的任何疑问。如果您想知道VPN和Smart DNS之间的区别，那么您将遇到麻烦！
VPN(VPNs)和智能 DNS(Smart DNS) 服务(Services)- 基础知识
术语“VPN”是Virtual Private Network的缩写。这是一项通过互联网创建受保护“隧道”的技术。连接两台计算机，就好像它们在同一个本地网络上一样。这与互联网通常的运作方式非常不同。
互联网(Internet)技术以“数据包”的形式传输数据，然后通过构成互联网的数百万台相互连接的计算机进行路由。因此，如果您通过电子邮件将图片发送给某人，它会在发送出去之前被分解成这些数据包。数据包是否无序到达并不重要，它们在另一端组装得很好。
但是，在到达目的地的路上，他们经过的每一台计算机都可以清楚地看到数据包的去向和来源。如果数据包没有加密，他们甚至可以看到内容！幸运的是，现在HTTPS加密技术几乎是普遍的，这种情况很少见。
这是什么意思？一方面，这意味着您的互联网服务提供商可以准确地看到您访问的网站，其他任何将这些数据包传递到目的地的人也可以看到。数据包的接收者（通常是目标服务器）也可以清楚地看到您的位置以及有关您的设备和互联网连接的其他事实列表。
VPN 服务通过额外的加密层对来自您设备的所有信息进行分层。(all )这意味着所有监视您的互联网连接的人都可以知道您已连接到VPN服务。他们根本不知道你在网上做什么。
“智能”DNS 是完全不同的鱼。它是域名系统(Domain Name
System)的缩写，是一种服务，它采用网站的纯地址并将其转换为您需要连接的服务器的特定 IP 地址。
通常您的ISP将是默认的DNS提供商，但您可以指定自己的首选DNS服务。谷歌(Google)拥有一个受欢迎的，人们喜欢它，这要归功于它的速度和可靠性。
SmartDNS可用于屏蔽您的 IP 地址，以便接收服务器看起来像您在真实位置之外的某个地方。“智能”位是指智能 DNS(Smart DNS)可以选择性的事实。因此，它只会掩盖您在特定网站列表中的位置。离开您不想隐藏您的位置的网站不受影响(don’t )。
VPN 和智能 DNS 有何相似之处
虽然这些技术非常不同，但从用户的角度来看， VPN(VPNs)和智能 DNS(Smart DNS)技术在您实际可以用它们做什么方面有一些相似之处。具体来说，您可以使用这两种技术来欺骗站点或服务，使其误以为您在不同的位置。
这使您可以绕过地理封锁，例如当某人仅向居住在世界特定地区的人提供视频时。
这适用于VPN(VPNs)，因为您连接的VPN服务器是目标站点所看到的。(VPN)如果该服务器在
美国(USA)，那么看起来您也在美国(USA)。大多数VPN服务允许您准确选择您的VPN服务器应该位于的位置，从而有效地让您选择要出现的区域。
SmartDNS有选择地拦截到您想要欺骗以为您在其他地方的网站列表的流量。然后，它们使您看起来好像位于您选择的区域中。
这就是这些技术相似的程度。然而，差异列表要长得多。
VPN 和智能 DNS(Smart DNS)服务(Services)之间的重要区别(Important)
您应该知道的第一个也是最重要的区别是智能 DNS不提供(Smart DNS)VPN提供的任何(none )隐私保护。您的网络流量没有额外的加密，您的ISP和与他们合作的任何人都可以轻松地看到您在做什么。
智能 DNS(Smart DNS)的唯一目的是为非常特定的网站欺骗您的位置。因此，您可以想象在公共WiFi上或访问您不想让其他人知道的网站时使用它是一个坏主意。
那么为什么要使用智能 DNS(Smart DNS)呢？好吧，这给我们带来了另一组重要的差异。智能 DNS(Smart DNS)将在任何允许您指定要使用的DNS的路由器上的路由器级别（覆盖所有连接的设备）工作。应该(Which)是所有这些。
另一方面，VPN仅适用于可以运行VPN客户端软件的专用路由器。如果您没有这些路由器之一，则必须在每台设备上单独运行VPN软件，这对于游戏机或Apple TV(Apple TVs)等设备并不总是可行的。
智能 DNS(Smart DNS)对连接性能的影响也可以忽略不计。如果当时有很多其他人也在使用该特定服务器，则通过加密隧道运行所有互联网流量可能会导致性能开销并使您陷入拥塞。智能 DNS(Smart DNS)不会做任何这些，因此根本不应该存在明显的性能问题。
底线
如果您只想为特定服务列表欺骗您的位置，那么智能 DNS(Smart DNS)是一个不错的选择。它们通常比VPN便宜，更容易设置，如果您想覆盖整个家庭，则不需要特殊硬件。
VPN(VPNs)是您可以获得的一些最强大的隐私保护工具。如果您想要完整的隐私包，并将位置欺骗作为额外奖励，它们是一个不错的选择。但是，从VPN中排除事物需要一种称为“拆分隧道”的功能，该功能可能很难设置。
他们需要前面提到的高端路由器来覆盖一个只有一个VPN连接的家庭，而如今大多数VPN服务都被流媒体提供商阻止了。也就是说，除非您为私有VPN IP地址支付额外费用，否则可以解决此问题。
这就是您在VPN(VPN)或Smart DNS之间做出明智决定所需的全部信息。当用于正确目的时，两者都是很棒的工具，但正如您所见，它们实际上是完全不同的技术！
What’s the Difference Between a VPN and Smart DNS?
In this day and age, who still uses a vanilla internet connectiоn? You dо? Well, don’t feel too bad about it. Most peoрlе are blіѕsfully unaware of their options when it comes to modifying their internet connections for bettеr safetу, privаcy or expanded capabilities.
However, if you do want to hide your internet activities or perform geo-unblocking of locked content, there are a few options on offer that might be a little confusing to total newcomers. Terms like “VPN” and “Smart DNS” are thrown around with gay abandon.
These technologies have some superficial
similarities, but work in fundamentally different ways. If you end up using the
wrong technology for your needs, it can have some serious consequences. So
let’s demystify the acronyms and settle any doubts you may have. If you want to
know the difference between a VPN and a Smart DNS, you’re about to hit paydirt!
VPNs and Smart DNS Services – The
Basics
The term “VPN” is short for Virtual Private Network. It’s a technology that creates a protected “tunnel” through the internet. Connecting two computers as if they were on the same local network. That’s very different from how the internet usually works.
Internet technology transmits data as “packets”, which are then routed over the millions of interconnected computers that make up the internet. So if you email a picture to someone, it gets broken up into these packets before being sent away. It doesn’t matter if the packets arrive out of order, they are assembled just fine at the other end.
However, on the way to their destination, every computer they passed through can clearly see where the packet is going and where it came from. If the packet is not encrypted, they can even see the contents! Luckily, with HTTPS encryption technology being virtually universal now, that’s a rare situation.
What does this mean? For one thing, it means
that your internet service provider can see exactly which websites you visit
and so can anyone else who passes those packets along to their destination. The
recipient of the packets, which is usually the destination server, can also
clearly see your location along with a list of other facts about your device
and internet connection.
A VPN service layers all of the information coming from your device with an additional
layer of encryption. This means that all anyone monitoring your internet
connection can know is that you are connected to the VPN service. They have no
idea what you are doing on the net at all.
A “Smart” DNS is a completely different kettle
of fish. It’s short for Domain Name
System and is a service which takes the plain address of a website and
translates it into the specific IP address of the server you need to connect
to.
Usually your ISP will be the default DNS provider, but you can specify your own preferred DNS service. Google hosts a popular one, which people like thanks to how fast and reliable it is.
A SmartDNS can be used to mask your IP address, so that it looks to the receiving server like you are somewhere other than your real location. The “smart” bit refers to the fact that the Smart DNS can be selective. So it will only mask your location for a specific list of websites. Leaving sites you don’t want to hide your location from unaffected.
How a VPN and Smart DNS are
Similar
While the technologies are very different,
from a user’s perspective VPNs and Smart DNS technology has some similarities
when it comes to what you can actually do with them. Specifically, you can use
both technologies to fool a site or service into thinking you are in a
different location.
This allows you to get around geoblocking,
such as when someone has only made a video available to people living in a
particular part of the world.
This works with VPNs, because the VPN server
you are connected to is what the target site sees. If that server is in the
USA, then it looks like you are also in the USA. Most VPN services let you
choose exactly what location your VPN server should be in, effectively letting
you choose a region to appear in.
A SmartDNS selectively intercepts the traffic
to a list of websites which you want to fool into thinking you are somewhere
else. They then make it appear as if you are located in the region of your
choice.
That’s the extent to which these technologies
are similar. The list of differences is however much longer.
The Important Differences Between
VPNs and Smart DNS Services
The first and most important difference you should be aware of is that a Smart DNS provides none of the privacy protection that a VPN does. Your web traffic has no additional encryption and your ISP and anyone they work with can easily see what you are doing.
The sole purpose of the Smart DNS is to spoof your location for very specific websites. So you can imagine it would be a bad idea to use it on public WiFi or while visiting sites you’d rather not have other people know about.
So why use a Smart DNS? Well, this brings us to another important set of differences. A Smart DNS will work at the router level (covering all connected devices) on any router that allows you to specify which DNS you want to use. Which should be all of them.
A VPN, on the other hand, only works on specialized routers that can run the VPN client software. If you don’t have one of these routers, you’ll have to run the VPN software on every device individually, which isn’t always possible for devices like game consoles or Apple TVs.
A Smart DNS also has a negligible effect on
connection performance. Running all of your internet traffic through an
encrypted tunnel can incur a performance overhead and subjects you to
congestion if plenty of other people are also using that particular server at
the time. A Smart DNS doesn’t do any of that and so there should be no
perceptible performance issues at all.
The Bottom Line
If all you want to do is spoof your location
for a specific list of services, then a Smart DNS is a great choice. They are
usually less expensive than a VPN, easier to set up and don’t require special
hardware if you want to cover your whole household.
VPNs are some of the strongest privacy protection tools you can get.If you want the total privacy package, with location spoofing as an added bonus, they are a good choice. However, excluding things from the VPN requires a feature known as “split tunneling”, which can be tricky to set up.
They need the aforementioned high-end routers to cover a household with a single VPN connection and these days most VPN services are blocked by streaming providers. That is, unless you pay a premium for a private VPN IP address, which gets around this issue.
That’s all you need to know to make an
informed decision between a VPN or Smart DNS. Both are great tools when used
for the right purposes, but as you can see they are actually totally different
technologies!
