大多数人都假设当您签署托管计划时，您会获得自己的 IP 地址，但事实并非如此。事实上，您需要为此注册一个专用 IP 地址。但什么是专用 IP 地址？
大多数托管软件包都会为您提供一个由许多其他客户共享的 IP 地址。这意味着互联网流量的带宽跨越多个网站。
在本文中，我们将深入研究专用 IP 和共享主机帐户之间的区别，并解释是否值得获得专用 IP。
什么是主机中的专用 IP 地址？(What Is a Dedicated IP Address In Hosting?)
大多数典型的托管计划价格低廉，因为托管公司可以在同一个 IP 地址放置多个托管帐户。这意味着一台服务器基本上专用于多个不同的客户。
专用 IP 地址是不同的，这意味着您将拥有自己的 IP 地址或服务器，专用于您的一个帐户。专用 IP 地址的成本更高，因为托管服务提供商必须为一个客户保留更多的服务器资源，但它通常会带来许多好处。
为您的网站使用专用 IP 地址有什么好处？(What Are The Benefits of Using a Dedicated IP Address For Your Website?)
对于普通客户来说，在共享主机计划上运行是一个很好的起点，但升级也有一些好处。让我们从共享计划的负面缺点开始。
当您使用共享计划时，您的 IP 地址将与其他客户共享。您的隐私和帐户详细信息是安全的，无法知道谁与您共享 IP 地址。但是使用共享 IP 地址确实会给您的网站性能带来风险。
首先，由于可能有多个网站的传入流量托管在单个服务器上，因此必须管理带宽。这些托管计划的最大上传和下载速度通常被限制在非常特定的水平，这样服务器就不会超载。
不幸的是，这意味着如果您从病毒式帖子或谷歌(Google)上表现良好的文章中获得流量高峰，流量可能会受到限制。用户可能需要等待更长时间才能加载您的网站，这样您的网站才不会对共享您相同 IP 地址的其他客户造成问题。
这会对您的用户保留率产生巨大的负面影响。页面速度得分很重要。因此，升级到专用 IP 地址可以阻止此问题的发生。
使用共享托管计划的另一个负面缺点是，您可能会因其他客户活动而干扰您的网站性能。
正如我们上面解释的那样，网站流量受到限制，这意味着如果事情按应有的方式运行，那么如果共享您的 IP 地址的客户突然流量激增，您应该不会看到任何严重的性能问题。但是技术并不总是按预期工作，并且不能保证其他客户活动不会引起问题。
一个例子可能是共享您的 IP 地址的客户成为DDOS 攻击(DDOS attack)的目标。由于您与该客户共享服务器，因此您的网站可能存在连接问题。
共享计划托管的另一个问题是共享的不仅仅是服务器网络速度。您还必须共享其他系统资源，包括存储。正因为如此，共享 IP 托管通常会极大地限制用户的存储大小，因此如果您继续上传新内容，将来您将无法扩展您的网站。
当然，专用 IP 地址将解决所有这些问题。使用专用 IP 地址，所有系统资源都专属于您，包括网络速度、内存和存储空间。
并非所有服务器的构建方式都相同，因此即使您计划拥有自己的专用IP 地址(IP Address)，您也必须确保服务器具有正确的硬件和网络要求来管理您的网站和传入流量。
专用 IP 托管还有其他好处。因为您是使用该服务器的唯一客户，所以您可以更好地控制它的运行方式，因为您不会影响任何其他客户的体验。您可以控制您的存储在您的网站上的分布方式并管理网络性能，以便随时准备好承受任何突然的流量高峰。
不同(Different)的托管帐户提供不同级别的支持，因此这可能意味着拥有专用 IP 地址需要更多的手动维护。但是您需要与每个服务器托管服务提供商联系以了解更多详细信息。
专用 IP 与共享主机 -(Shared Hosting – Which)哪个更好(Better)？
应该清楚的是，专用 IP 地址比共享主机有很多好处，但它总是明确的选择吗？下面我们来看看流行的提供商Bluehost上的专用 IP 托管和共享服务器托管之间的定价和性能差异。(Bluehost)
专用 IP 托管的统计数据(The Stats of Dedicated IP Hosting)
- 价格从 119.99 美元到 209.99 美元不等
- 4 核 @ 2.3GHz – 3.3GHz
- 500GB 到 1TB 镜像存储
- 4GB-16GB 内存
- 5TB-15TB带宽
- 3-5 个唯一的 IP 地址
共享主机的统计数据(The Stats of Shared Hosting)
- 价格从 7.99 美元到 23.99 美元不等
- 没有专用 IP 地址
- 存储、性能和网络受到限制
Bluehost对其带宽和存储使用“无限”或“不计量”等术语。这意味着Bluehost监控客户在共享计划中的平均性能，并确保他们的服务器可以根据这些数据支持使用它的客户。虽然您的带宽和存储在技术上是无限的，但如果您超出了他们认为的正常使用范围，Bluehost会与您联系并要求您将其调低一点。
对于大多数人来说，仅成本差异就是为什么共享主机就足够了。除非您正在运行一个受欢迎的网站，否则专用托管不是必需的。但是，如果您开始增加更多流量，升级到专用主机可能是值得的投资。
我们希望我们能够向您解释专用主机，并帮助您做出是否升级的决定。如果您对此有任何疑问，请务必在下面发表评论。
HDG Explains : What Is a Dedicated IP Address & Should I Get One?
Mоst people are under the assumption that when уou sign fоr a hоsting plan, you get your own IP address, but that’ѕ not true. The truth iѕ you need to sign up for a dedicated IP address for that. But what is a dedicated IP address?
Most hosting packages will give you an IP address that’s shared by a number of other customers. This means that the bandwidth for internet traffic is stretched across multiple websites.
In this article, we’ll take a deeper look at the difference between a dedicated IP and a shared hosting account, and explain whether it’s worth getting a dedicated IP or not.
What Is a Dedicated IP Address In Hosting?
Most typical hosting plans come at a low price because the hosting company can place multiple hosting accounts at the same IP address. This means that one server is essentially dedicated to multiple different customers.
A dedicated IP address is different and it means you’ll have your very own IP address, or server, dedicated to your one account. It costs more for a dedicated IP address because the hosting provider must reserve more server resources for just one customer, but it usually comes with a number of benefits.
What Are The Benefits of Using a Dedicated IP Address For Your Website?
For the average customer, running on a shared hosting plan is a great place to start, but there are some benefits to upgrading. Let’s start with the negative drawbacks of a shared plan.
When you’re on a shared plan, your IP address is shared with other customers. Your privacy and account details are safe and there’s no way to know who is sharing an IP address with you. But using a shared IP address does pose a risk to your website performance.
Firstly, because there could be multiple websites with incoming traffic hosted on a single server, bandwidth has to be managed. The peak maximum upload and download speeds are often restricted to very specific levels with these hosting plans so that the servers don’t become overloaded.
Unfortunately that means that if you hit a spike in traffic from a viral post or a well performing article on Google for example, traffic may be throttled. Users may have to wait longer for your website to load so that your site isn’t causing issues to other customers sharing your same IP address.
This can have a huge negative impact on your user retention. Page speed score is important. So upgrading to a dedicated IP address can stop this issue from ever happening.
Another negative drawback to using a shared hosting plan is that you may risk interference to your website performance as a result of other customer activity.
As we explained above, website traffic is throttled which means if things work like they should, you shouldn’t see any drastic performance issues if a customer sharing your IP address suddenly has a surge in traffic. But technology doesn’t always work as expected, and there’s no guaranteeing other customer activity may not cause issues.
One example could be if a customer sharing your IP address is targeted by a DDOS attack. Because you’re sharing a server with that customer, your website could have connectivity issues.
Another issue with shared plan hosting is that it’s not just the server network speeds that are shared. You also have to share other system resources, including storage. Because of this, shared IP hosting often limits a user’s storage size quite significantly, so you’ll have trouble expanding your website in the future if you keep uploading new content.
Of course, a dedicated IP address will resolve all of these problems. With a dedicated IP address, all system resources are dedicated only to you, including network speed, memory, and storage space.
Not all servers are built the same, so even if you plan to have your own dedicated IP Address, you must make sure the server has the right hardware and network requirements to manage your website and incoming traffic.
Dedicated IP hosting also has other benefits. Because you are the sole customer using that server, you are given greater control over how it operates because you won’t impact any other customer’s experience. You can control how your storage is distributed across your websites and manage network performance so you’re always ready to endure any sudden spikes in traffic.
Different hosting accounts offer different levels of support, so it may mean that owning a dedicated IP address requires more manual maintenance. But you’ll need to check with each server hosting provider to find out more details about that.
Dedicated IP vs Shared Hosting – Which Is Better?
It should be clear that a dedicated IP address has a number of benefits over shared hosting, but is it always the clear choice? Below we’ve taken a look at pricing and performance differences between dedicated IP hosting and shared server hosting on Bluehost, a popular provider.
The Stats of Dedicated IP Hosting
- Pricing from $119.99-$209.99
- 4 Cores @ 2.3GHz – 3.3GHz
- 500GB to 1TB mirrored storage
- 4GB-16GB RAM
- 5TB-15TB bandwidth
- 3-5 unique IP addresses
The Stats of Shared Hosting
- Pricing from $7.99-$23.99
- No dedicated IP address
- Storage, performance, and network throttled
Bluehost uses terms like “unlimited” or “unmetered” for its bandwidth and storage. What that means is that Bluehost monitors the average performance of their customers on shared plans and ensures that their servers can support the customers using it based on this data. And while your bandwidth and storage is technically unlimited, if you go outside of what they consider normal usage, Bluehost will contact you and ask you to tone it down a little bit.
For most people, the cost difference alone is why shared hosting is more than enough. Unless you’re running a popular website, dedicated hosting isn’t nessacary. But if you start to ramp up more traffic, upgrading to dedicated hosting can be a worthwhile investment.
We hope that we’ve been able to explain dedicated hosting to you and help you make a decision on whether to upgrade or not. If you have any more questions about it, make sure to leave a comment below.
