Hey everyone! Within this piece, the FlexCard virtual card service team dives deep into the realm of proxy servers, elucidating their purpose and unveiling 10 complimentary proxy service providers for your perusal.

What is a proxy server?

A proxy server functions as an intermediary between your device and the internet, channeling outgoing traffic through its system. Acting as a bridge, it enables you to conceal your IP address, which typically discloses your geographic location and Internet Service Provider (ISP) details. Instead, when accessing the web through a proxy, your connection appears to originate from a different IP address. Consequently, observers perceive only the proxy's information, shielding your device's identity. This feature not only preserves your anonymity but also facilitates circumvention of location-based restrictions.

Why do you need a proxy for affiliate marketing?

Proxy servers play a pivotal role in affiliate marketing by circumventing security measures implemented on advertising platforms like Google Ads or Facebook. Without proxies, webmasters encounter challenges in creating numerous accounts from a single IP address, particularly when platforms prohibit multiple account usage. For instance, if Facebook detects multiple accounts originating from the same IP address, it can swiftly block all associated accounts. Utilizing proxies mitigates these issues.

Proxy servers empower affiliates to:
  • Launch advertising campaigns promoting products from restricted categories.
  • Create multiple accounts on a single advertising platform.
  • Mimic activity from diverse devices.
  • Employ parsing services.
  • Conceal personal data to ensure secure usage of social networks.

IPv6 and IPv4 – which one to choose?

Based on the classification of address protocols, there exist two distinct iterations of proxies - IPv6 and IPv4. IPv4, the earlier iteration, furnishes 32-bit IP addresses akin to "". Conversely, IPv6 boasts novel 128-bit addresses exemplified by "fe80:10:0:33:200:f8ff:fe21:67cf", presenting an extensive array of distinct addresses apt for various endeavors, such as pharming Facebook accounts. IPv6 is acknowledged as a more contemporary protocol. Nevertheless, if the system you are engaging with lacks support for IPv6, it is advisable to resort to IPv4 to mitigate compatibility dilemmas.
