As it says in the name, IPv4 proxies operate based on the original Internet protocol (version 4) that has been the common communications protocol for all devices connected to the Internet since the eighties. This protocol is 32-bit and, therefore, is limited to 4.2 billion IPs around the Globe. This fact makes the IPv4 proxies more versatile and limited when compared to IPv6 proxies.
If we consider the use cases of IPv4 proxies (normally residential IPs), then we will see pretty much the whole spectrum of cases common to private proxies.
When used as rotating proxies, IPv4 IPs demonstrate great performance in getting access to websites for scraping and harvesting missions. You can buy an IPv4 address with sticky sessions and use it while scraping data in browsers for an extensive period of time without raising red flags.
When you buy IPv4 proxies they can also be perfect for use inside bots that help you automate your online missions.
You can also get IPv4 proxies for such marketing tasks as ad verification. With these proxies, you will be able to track the performance of your ads and look at the competition in countries of your choice.
When it comes to selecting an optimal set of paid proxies for your online mission, you might face a very tricky question: whether to go for residential proxies or datacenter proxies will do the job alright?
