When many enterprises conduct brand monitoring, data enrichment, potential customer generation and large-scale marketing analysis, they will use web data capture technology to quickly extract data from multiple websites for analysis and control. In order to ensure fast and smooth web capture, they will use proxy services. The main reasons are as follows:
Visit sites whose content is limited by geography. If you want to crawl some regionally restricted web sites, you need a proxy server to do this. Not only that, but with the help of the proxy, you are free to choose any location provided by the proxy server of your choice. This way you won't be banned by websites that can't detect you using web scraping tools.
There are several types of proxies to choose from:
1.Data center proxy
Data center proxies are virtual IP addresses created in powerful server hubs. They don't have any Internet service provider information associated with them. These proxies are usually banned because their connections look like fake Internet traffic. Because of the frequency with which data center proxies are used for DDoS attacks, they are poorly packaged. The proxies also share a subnet (for example, a Class C subnet is represented by the number 14 in these IP addresses: 18.104.22.168, 22.214.171.124).
Residential proxies are the highest quality proxies because they look like real mobile or desktop devices. In fact, they are real devices. Each residential IP is a device that acts as a proxy server. For any site, traffic from residential proxies looks just like you and me.
An anonymous proxy is the type of proxy that does not send your identity information to the target server. It pretends to be an actual user, rather than a non-anonymous proxy, which notifies the server that it is a proxy.
Transparent proxy does not change the IP address of the client. They are typically located between a public Wi-Fi network and devices on the Internet. Transparent proxies typically act as gatekeeper proxies , authenticating users and granting them access to the network.
To sum up, the risk of detection using a data center proxies is relatively small, but if you want to keep the chance to zero, then residential IP proxy is best for you. The Residential IP proxy comes with a legitimate IP address and will not blacklist you from the site. In the case of a data center proxy, the site owner can detect that it belongs to the data center and not the ISP.
