当您从当地互联网服务提供商(Internet Service Provider)( ISP ) 注册互联网服务时，您会获得一个IP 地址(IP address)。就像您的家庭住址(home address)一样，这可以让您的设备浏览互联网并帮助识别您网络上的特定设备。
通常，您的ISP 会(ISP)为您的连接提供动态IP 地址(IP address)。但是，有时静态IP 地址(IP address)比通常的动态IP 地址(IP address)更有效。
您如何确定要使用哪个IP 地址(IP address)，以及是什么让一个比另一个更好？让我们仔细看看静态 IP 与动态 IP 之间的区别，以及各自的优势。
1.静态IP是永久的。随着时间的推移动态 IP 变化(Static IP Is Permanent. Dynamic IP Changes Over Time)
首先，我们需要定义每种IP 类型(IP type)的作用，以便更好地理解其功能。动态IP 地址(IP address)是两者中较常见的一种，因为ISP(ISPs)默认向其客户提供这种类型的 IP。
由动态主机配置协议(Dynamic Host Configuration Protocol)( DHCP )自动提供的动态 IP 不是永久性的(dynamic IPs are not permanent)，并且会定期更改，而不会影响您的Internet 连接(internet connection)。
与其动态对应物相反，静态IP 地址(IP address)保持不变，即使设备没有主动连接到网络或关闭，也不会改变。您的 ISP 会根据您所在地区的可用性将此IP 地址(IP address)直接分配给设备。
除非取消IP 地址(IP address)的保留或设备永久退出网络，否则该设备的IP 地址(IP address)将保持不变。
2.动态IP自动给出(Dynamic IPs Are Given Automatically)
连接到网络的每个设备，无论是家庭网络还是在线(home network or online)设备，都会由DHCP 服务器(DHCP server)立即分配一个动态IP 地址(IP address)，并识别其网络中的特定设备。
自动设置使连接到互联网更容易且无压力，因为它省去了在服务器上手动设置设备的麻烦。使用静态IP(IPs)，每个IP 地址(IP address)都是手动配置的，不能在其他设备上重复使用。
3.静态IP使远程连接更容易(Static IPs Make Remote Connections Easier)
静态 IP 相对于动态 IP 的另一个优势是互联网连接的稳定性和可靠性(stability and reliability)。静态 IP 是永久IP 地址(IP address)，使您的连接更容易通过域名系统 (DNS)(Doman Name System (DNS))找到。这使得静态IP 成为(IP ideal)企业、网络托管(web hosting)和维护游戏或网络服务器(game or web servers)的理想选择。
使用静态 IP 时，通过Internet 协议(Internet Protocol)语音(Voice)( VOIP ) 进行呼叫、连接到虚拟专用网络(Virtual Private Networks)( VPN ) 以及管理远程桌面任务(managing remote desktop tasks)更易于管理。通过静态 IP 在对等服务器之间进行 文件传输的速度更快。(File)
4.动态IP不太容易被黑客攻击(Dynamic IPs Are Less Prone to Hacking)
在当今时代，几乎每个人都以一种或另一种形式在线，让您的设备被黑客入侵的威胁比以往任何时候都更加真实。黑客进入一个人的设备的一种常用方法是通过其IP 地址(IP address)，这就是拥有静态IP 与(IP vs). DHCP IP 地址(DHCP IP address)可能是危险的。
由于静态IP(IPs don)除非有意删除，否则不会更改(t change)，因此一旦黑客找出服务器信息(server information)，就无法阻止他们攻击该连接。这可能意味着文件和个人数据的潜在损坏或被盗(corruption or theft)、敏感信息泄露以及资金损失。
虽然动态 IP 地址不是消除黑客攻击的完美解决方案，但它们提供比静态 IP 更好的安全性。由于它会定期更改，因此不太容易受到网络攻击，并且黑客更难以查明您的确切位置。
5.静态IP成本更高(Static IPs Cost More)
与动态 IP 地址相比，从您的ISP请求静态(ISP)IP(IPs)通常会在您的账单上产生额外费用。这是由于需要设置、维护和额外的跑腿工作。
将 IP 地址想象为您的典型停车位(parking space)。动态IP(Dynamic IPs)是院子里的空置停车位，而静态IP(IPs)是预留停车位。它们的数量有限，因为这些 IP 地址不能重复使用，拥有一个需要订阅。
可用的IP(IPs)数量不足以让全球所有设备都拥有专用 IP 地址。这就是ISP(ISPs opt)不时选择回收IP的原因。(IPs)由于他们无法重用静态IP(IPs)，因此他们必须重视 IP 以进行持续维护和维护。

所有这些关于静态与动态 IP 的讨论都会激发人们对了解您的IP 地址(IP address)以及是否可以将其从动态更改为静态的兴趣。有几个在线站点可以显示您的公共IP 地址(IP address)。
为家庭网络上的设备使用静态 IP 的一些好处(Some Benefits of a Static IP for Devices on Your Home Network)
对于家庭网络，您还可以将网络内的IP 地址(IP address)从动态 IP 更改为静态 IP，以改善网络内的连接性。此外，如果您使用的是VPN，服务中还有用于检查和更改IP 地址(IP address)的选项。
DHCP（动态主机配置协议(Dynamic Host Configuration Protocol)）无缝地为连接到路由器的任何设备分配一个新的IP 地址。(IP address)但是，手动将您自己的静态 IP 分配给家庭网络(home network)中的设备也可以通过多种方式让生活更轻松。通过路由器为您自己的设备 手动设置静态IP(IPs)很容易。
例如，如果您使用Kodi设置了媒体服务器，那么最好从路由器的接口为其分配一个静态IP 地址。(IP address)统一的静态IP 寻址(IP address)方案还可以帮助您通过命令行工具或任何其他IP 通信(IP communication)方法轻松找到您的设备。
选择适合您需要的 IP 地址(Choosing the IP Address That Suits Your Needs)
选择正确的IP 地址(IP address)类型取决于您使用互联网的方式。如果您更像是上网查看社交媒体、观看视频(watch videos)和玩一些游戏的休闲互联网用户，那么动态(internet user)IP 地址(IP address)将非常适合您。它是免费的、自动的，并且可以完成工作。
但是，如果您是一家企业并且需要(business and require)稳定的连接以提高生产力和网站(productivity and website)或服务器的维护，那么使用静态 IP 是您的最佳选择。虽然它可能比标准动态IP 地址(IP address)花费更多，但专用 IP 可以改善连接性并使您的服务器更容易被其他企业找到。探索您的ISP的定价层级，因为商业ISP计划通常包括选择静态 IP 的选项。
Static IP vs. Dynamic IP Addresses (DHCP) – 5 Big Differences
When you sign up for internet service from your lосаl Internet Service Proνider (ISP), you’re asѕigned an IP address. Like yоur homе аddress, this lets your device navigate the internet and help identify a specific device on your network.
Typically, your ISP provides a dynamic IP address for your connection. However, there are times that a static IP address works better than the usual dynamic IP address.
How do you determine which IP address to use, and what makes one better than the other? Let’s have a closer look at the difference between static vs. dynamic IP, as well as the strong points for each one.
1. Static IP Is Permanent. Dynamic IP Changes Over Time
First, we need to define what each IP type does to understand its function better. A dynamic IP address is the more common of the two, as ISPs provide this type of IP by default to their customers.
Given automatically by the Dynamic Host Configuration Protocol (DHCP), dynamic IPs are not permanent and periodically change without affecting your internet connection.
Contrary to their dynamic counterpart, static IP addresses stay the same and do not change even if the device is not actively connected to the network or turned off. Your ISP assigns this IP address directly to the device based on availability in your area.
Unless the reservation for the IP address is canceled or the device is permanently taken out of the network, that device’s IP address would remain the same.
2. Dynamic IPs Are Given Automatically
Each device that connects to the network, whether a home network or online, is immediately assigned a dynamic IP address by the DHCP server and identifies the specific device within its network.
The automated setup makes connecting to the internet more accessible and stress-free, as it saves the hassle of manually setting up devices on the server. With static IPs, each IP address is manually configured and can’t be reused on other devices.
3. Static IPs Make Remote Connections Easier
Another advantage that static IP has over dynamic IP is the stability and reliability of the internet connection. A static IP is a permanent IP address, making your connection easier to locate via the Doman Name System (DNS). This makes static IP ideal for businesses, web hosting, and maintaining game or web servers.
Making calls over Voice over Internet Protocol (VOIP), connecting to Virtual Private Networks (VPN), and managing remote desktop tasks are more manageable when using static IP. File transfers are faster between peer-to-peer servers over static IP.
4. Dynamic IPs Are Less Prone to Hacking
In today’s age, where almost everyone is online in one form or another, the threat of getting your device hacked is more real than ever. A common method for hackers to get into a person’s device is through its IP address, and this is where having a static IP vs. DHCP IP address could be a danger.
As static IPs don’t change unless intentionally removed, once a hacker figures out the server information, there’s no stopping them from attacking that connection. This could mean potential corruption or theft of files and personal data, compromised sensitive information, and lost funds.
While dynamic IP addresses are not the perfect solution to eliminate hacking, they offer better security than a static IP. Since it changes periodically, it is less prone to cyberattacks and more difficult for hackers to pinpoint your exact location.
5. Static IPs Cost More
Compared to dynamic IP addresses, requesting static IPs from your ISP would generally have an additional charge on your bill. This is due to the setup, maintenance, and extra legwork needed.
Think of IP addresses like your typical parking space. Dynamic IPs are the vacant parking spots on the yard, while static IPs are reserved parking spots. There’s a limited quantity of them as these IP addresses can’t be reused, and having one would require a subscription.
The number of IPs available isn’t enough for all devices worldwide to have dedicated IP addresses. That’s why ISPs opt to recycle IPs from time to time. Since they can’t reuse static IPs, they have to place a premium on the IP for constant maintenance and upkeep.
Protip: How to Check and Change IP Address on Home Networks
All these talks about static vs. dynamic IP would spark interest in knowing your IP address and if it’s possible to change it from dynamic to static. There are several sites online that can show your public IP address.
Some Benefits of a Static IP for Devices on Your Home Network
For home networks, you can also change the IP addresses within your network from dynamic to static IP to improve connectivity within the network. Also, if you’re using a VPN, there are options within the service for checking and changing the IP address.
DHCP (Dynamic Host Configuration Protocol) seamlessly assigns a new IP address to any device connected to the router. But manually assigning your own static IP to the devices in your home network can make life easier in several ways too. It’s easy to manually set static IPs for your own devices from the router.
For instance, if you have set up a media server with Kodi then it’s better to assign it a static IP address from the router’s interface. A uniform static IP addressing scheme can also help you easily find your devices via command-line tools or any other IP communication method.
Choosing the IP Address That Suits Your Needs
Selecting the correct IP address type is based on how you use your internet. If you’re more of a casual internet user that goes online to check social media, watch videos, and play some games, then a dynamic IP address will work well for you. It’s free, automatic, and gets the job done.
However, if you’re a business and require stable connectivity for productivity and website or server upkeep, then going with a static IP is your best move. While it could cost more than a standard dynamic IP address, a dedicated IP improves connectivity and makes your server easier to locate for other businesses. Explore your ISP’s pricing tiers as business ISP plans often include the option to opt for a static IP.
