擴展的答案
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.
什麼是數據中心代理？
想像一個大倉庫，裡面堆滿了電腦，燈光閃爍，空氣中瀰漫著互聯網的氣味......
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.
它們旨在存儲數據（因此得名）——但互聯網通常對它們有更大的計劃。其中一些計劃包括非法或禁止的活動。
問題是 - 網站可以輕鬆識別數據中心代理。
那麼有什麼大不了的呢？
好吧，其中一些網站對任何使用數據中心代理的人都採取“先拍後問”的態度。
並禁止他們用桶吸煙。
數據中心代理如何工作？
在大多數情況下，您會收到要插入瀏覽器擴展的IP位址清單。啟動后，您的 Web 流量將路由到數據中心代理，繼承其 IP 位址，並繼續傳輸到 Web。這樣，您的網路活動看起來就像來自代理。
資料中心代理有兩種常規類型：
共用
共用意味著您與其他用戶共用代理。可以想像，他們被列入黑名單的可能性更高，而且速度往往更慢。權衡是它們的成本更低——所以這很好。
私人
你把這個都留給自己。更貴，但除了您之外，沒有其他人會使用該代理。不過，最好從誠實的轉銷商那裡獲得這些，因為它們可能有不好的歷史並且永遠不起作用。
還有一個處女代理，或者更準確地說：
新代理
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.
優勢
- 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.
弱點
- 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.
使用數據中心代理的最佳方式
- 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?
什麼是住宅代理？
住宅代理具有官方住宅 IP 位址。這是官方的，因為ISP已將IP地址註冊為真人。出於這個原因，住宅代理不會引起網站安全的過度關注。
住宅代理如何工作？
供應商的代理伺服器將您連接到其網路中適合您條件的代理，然後您的流量通過它路由到 Web。您將從該代理來自的任何地方訪問網路，並使用其IP位址。
輪換住宅代理
這隻是意味著您將從一個住宅代理切換到另一個住宅代理。您發出的每個請求都可能看起來來自不同的使用者，因此很難密切關注您的活動。您還可以設置為每隔幾分鐘旋轉一次，或者隨時旋轉。
但是，30 分鐘大約是您可以使用輪換代理的最大時間——有一個名稱：
粘性會話
保留一個住宅IP位址一段時間很有用。通過粘性會話可以結帳在線商店或創建新帳戶。
優勢
- 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.
弱點
- 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?
你繼續旋轉。這不是世界末日，除了他的手機剛剛受到創傷。
使用住宅代理的最佳方式
- 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.
