These include: Pricing, if the use case requires a large number of unique IP addresses and IP address diversity if comparing to peer-to-peer residential networks.
ISP and Static Residential proxies have several benefits over basic proxy servers and standard peer residential networks, however, there are some drawbacks that should be considered:
Pricing: Since ISP/Static Residential proxies are charged by IP address rather than bandwidth, their cost can be significant for use-cases that require a large number of unique IP addresses.
IP Address Diversity: ISP/Static Residential proxies are owned by providers like ourselves in sequential blocks called subnets. Our static ISP pool has a large variety of subnets (Over 350+), however, this is still limited when compared to peer-to-peer residential networks which can be made up of millions of IP addresses, each from different subnets.
Limited Locations: Providers of ISP / Static Residential proxies incur large fixed costs in each location they have connectivity. This tends to limit the number of locations that can be offered by providers.
