    if a single IP address and device sends out a suspiciously big amount of requests in a short period of time then it is most likely a bot. When you change the proxy server that your web scraper uses you change the IP address under which the scraper visits the site, thus the website thinks that it is being accessed from different locations. Web scrapers also use HTTP header rotation, HTTP headers contain basic information about your device whenever you send a request to the website, thus changing both of these identifiers makes it look like many different devices from different locations are accessing the site and thus it is very hard to block.

    Main Uses:

    1.Pass the filters and censorship

    If you are in the US, you may additionally now not be capable of setting up the apps that are presented to Indian customers on the Apple Appstore. This is due to the fact the server makes use of an IP-based geographic area to restrict the right of entry to the provider to a positive region. Companies use this tactic to provide customized offerings to customers in a given market. And at the authorities level, this can be used to censor, to block sure content material coming from a positive region. A proxy server can conceal your identification using sending requests on your behalf to avert this restriction, the use of some other IP that has to get entry to the offerings you want.

    2.Anti-blocking with IP rotation

    When you browse a website, the server can understand typical visits at an uncommon stage as malicious actions. To forestall the server from being overloaded with this heavy traffic, particularly using net scraping bots, many websites now take anti-scraping measures to block uncommon visitors. However, the Internet considers every IP to be a special vacationer and if you are altering IP, you are having a difficult time detecting their activities. Browse the internet site for the usage of more than one IP, manage your visits inside a regular level. This is how humans use IP rotation to keep away from being blocked.

    If you need multiple different proxy IP, we recommend using RoxLabs proxy.
