What are the challenges in protecting against bots that use residential IP addresses?

Identifying bots that use residential IP addresses presents challenges because these bots can appear more legitimate compared to those using data center IP addresses. Residential IPs are more difficult to distinguish from real users since they are assigned to home connections rather than data centers. Additionally, residential IP addresses are less likely to be blacklisted or identified as malicious since they are associated with legitimate users. This makes it challenging for detection systems to differentiate between real users and bots using residential IPs, leading to potential issues with accurately identifying and blocking malicious bot activity.
