扩展答案
Data center and residential proxies mask your IP address with their own to make it look like you’re accessing the web from a different location. It may sound simple, but this allows you to bypass geo-blocks, disarm anti-crawling software, bend the rules of social networking accounts, and get past bans or suspensions on eCommerce sites.
什么是数据中心代理？
想象一个堆满电脑的大仓库，灯光闪烁，空气中弥漫着互联网的味道......
That’s where data center proxies live. Not out in the real world, but on cloud servers, virtual private servers, and the like. Their IP addresses are bought in bulk from corporations like Digital Ocean or Amazon AWS.
它们是用来存储数据的（因此得名）--但互联网往往对它们有更大的计划。其中一些计划包括非法或违禁活动。
问题是，网站可以轻松识别数据中心代理。
有什么大不了的？
有些网站对使用数据中心代理服务器的人采取 "先斩后奏 "的态度。
并禁止他们在桶内吸烟。
数据中心代理如何工作？
在大多数情况下，您会收到一份 IP 地址列表，将其插入浏览器扩展程序。一旦激活，您的网络流量就会进入数据中心代理，继承其 IP 地址，然后继续上网。这样，你的网络活动看起来就像是来自代理。
数据中心代理一般有两种类型：
共享
共享是指您与其他用户共享代理。可以想象，它们被列入黑名单的几率会更高，速度也会更慢。但它们的成本更低，这一点很好。
私人
你可以独享这一个。虽然价格较贵，但除了你，没有其他人会使用代理服务器。不过，最好从诚实的经销商那里购买，因为它们可能有不良记录，永远无法使用。
还有一个处女代理，或者更准确地说：
新鲜代理
Fresh proxies are private data center proxies held for at least six months to ensure they’re clean and aren’t on any naughty lists. Perfect for managing multiple accounts.
优势
- Fast – They’re fueled by powerful servers and can offer speeds of up to 10 GB per second.
- Predictable – Data centers don’t sleep, so you can expect very little downtime, if any.
- Cheap – You can buy a private data center proxy for as little as $1 and shared ones for fractions of that.
- Private – You’re can get private proxies that haven’t be abused by anyone else.
- Unlimited traffic – In most cases, you only have to pay for the IP address.
弱点
- High ban risk – Data center IP addresses are issued in subnets. So when one IP address is banned, there’s a good chance all 256 in the group will also be banned.
- Low trust – Websites can easily detect data center IP addresses and will keep a tight watch on them. Sometimes they won’t even give you that courtesy, and ban you before you step through the door.
- Not user-friendly – You’ll have to procure the IP addresses and plug them into your browser. Then if they do work, you have to manually juggle them around to web scrape, sneaker bot, change locations and all that jazz.
- Few locations – When’s the last time you even saw a data center? There’s aren’t very many – less than 3000 in the US – which limits where you can browse from.
使用数据中心代理的最佳方法
- Web scraping – If you know how to work around anti-crawler protection and have experience with manual proxy rotation, you can benefit from cheaper prices and faster speeds. However, it’s not as efficient as residential proxies.
- Sneaker bots – The only reason I put this here is for speed and cost. It’s cheap so you can fail more at a discounted price, and you may get a shoelace-wide jump on the competition.
- Managing accounts – Whether you create numerous profiles for a social media empire or outmaneuver eCommerce restrictions, fresh proxies are best to ensure multiple accounts live out long lives.
- Gaming – High speed, unlimited bandwidth. Need I say more?
什么是住宅代理？
住宅代理服务器有一个正式的住宅 IP 地址。说它是官方的，是因为 ISP 已将 IP 地址注册给了一个真实的人。因此，住宅代理不会引起网站安全的过度关注。
住宅代理如何工作？
服务提供商的代理服务器会将您连接到其网络中符合您要求的代理，然后您的流量会通过该代理进入网络。您可以通过代理服务器的 IP 地址访问网络。
轮流居住代理
这只是意味着你将从一个住宅代理切换到另一个住宅代理。您的每个请求看起来都来自不同的用户，这就很难监控您的活动。您还可以设置每隔几分钟或随时轮换。
不过，30 分钟是您使用轮换代理所能花费的最长时间--有一个名字叫 "轮换代理"：
粘性会议
暂时保留一个住宅 IP 地址非常有用。在网上商店结账或创建新账户时，可以使用粘性会话。
优势
- Highly trusted – Websites can’t tell residential proxies and real users apart. This allows you to mask your identity without raising any eyebrows.
- Many locations – Well established proxy providers have access to millions of residential proxy pools all over the world. Not only can you access the internet from anywhere, but you can also rotate within local networks.
- User-friendly – You don’t have to do much. Plug into your provider’s proxy server, select your location, set your rotation frequency, and that’s it. Web scraping becomes web chillin’ when rotation’s on auto-pilot.
- Ban-free – As long as you don’t go nuts, residential proxies prevent account bans and suspensions if you want to create multiple accounts, scrape web data, or cop sneakers with a bot.
弱点
- Pricey – It costs way more than a dollar. And it should. It takes resources to make it all happen safe and effectively.
- Slower – These don’t have data center horsepower – yet. You’re going to rely on the proxy owner’s internet speed. However, if their speed doesn’t blow your socks off, you can always rotate.
- Unreliable connection – Even though sticky sessions are a thing, and you control rotation frequency – what if the proxy owner drops their phone in a toilet – or drops connection in another, more likely way?
你继续旋转。这又不是世界末日，只是手机受到了创伤的老乡除外。
使用住宅代理的最佳方法
- Creating multiple stealth accounts – You need a residential IP address each time you create a new account. Data center IPs won’t do – platforms like eBay and Amazon are on to them. But after you create a new account, get yourself a fresh proxy to manage it long term.
- Sneaker botting – In this highly competitive game of copping sneakers, you want speed and authenticity. Residential proxies are authentic, but usually not as fast as data center proxies. So the pros use a mix of both.
- Web scraping – Hands down the easiest way to scrape the web and collect data. With many more locations and the ability to rotate IP addresses after each request, they offer the most vast and comprehensive results.
- Bypass geo-blocks – You can access the web from anywhere in the world – as a real user. It is however unnecessarily expensive for some purposes like streaming Netflix or Twitch.
