1.In a proxy network, a proxy server acts as a gateway, forwarding requests from proxy users to any number of outbound (exit) nodes and then on to the target site. The exit node is the alternate IP address, and by swapping one IP for another, you can show up as a completely different user in your chosen geographic location. When blocking your previous IP, proxy users are able to verify the accuracy of information when collecting data, access location-specific content, such as advertising or pricing information, and simulate different online environments when testing the site.
2. When you enter the address or URL of a site, you request access to the domain. This request provides information to this particular domain from your device, cookie, and most importantly, IP address. Your IP address is similar to a mailing address and contains information about how to get the information you requested back to you. IP addresses provide location data, so sites can respond by providing web page content relevant to you.
If you need multiple different proxy IP, we recommend using RoxLabs proxy, including global Residential proxies, with complimentary 500MB experience package for a limited time.
