Data center IP is known as the computer room, that is, the common vps (virtual private server) or independent server, whose address is marked as hosting. Some companies' Intranet exit IP may be marked as the business IP "business".

Why does a residential IP enable a particular service?
First, access is restricted when the target we are accessing is strongly protected.
For example: if several people access a Google service over a data center IP, Google will issue a challenge to each terminal: Please prove that you are a person! I'm sure you all have.
When multiple people access Google services from a single home IP, it doesn't question, and Google assumes that this is the normal behavior of several people.
Compared to search engines, social networking sites, financial banks, e-commerce sites, advertising alliances, market research and other sites have higher IP quality requirements! When we sign up for Facebook AD background, nine times out of ten we have encountered Facebook directly blocking accounts, requiring you to upload a clear picture of your face to prove that you are you, this is also the IP problem.
By now you know how social media accounts FB, IG, Reddit, Viber, etc., keep getting blocked and tiktok gets zero views. The system has decided that you're not a real user at all!
One way to think about it is that any company that wants real registered users doesn't want the data center IP registration to be a waste of resources, because the accounts registered from the data center IP are not normal users, right?
Therefore, some enterprise websites will restrict data center IP as one of the most important access restrictions to prevent robot behavior.
On the contrary, at that time, it was also sad that the possibility of being blocked was relatively small. Of course, the cpa business of social media registration was just an example of the application of residential ip. When we used the program to capture the data of competing products, we also needed residential ip, so that our rivals would think that customers were browsing product data, rather than being crawled!

Having said so much, I think you should also know that the rental of residential IP, as of now, the global daily total demand value of residential IP is about $3-5 million, residential IP is widely used in data acquisition, social media operations, seo optimization, market research, brand protection and other fields.
