1. The server built. The advantage of this connection method is that the effect is the most stable, timeliness and area can be completely controlled, can be carried out according to their own requirements, and match the depth of the product. But the most obvious disadvantage is that crawlers need to be able to maintain proxy servers, so here comes the problem. First, they need to spend a lot of time to maintain. Second, the cost problem, their own construction cost is very high, but invested a lot of maintenance time and construction energy, as well as the high cost after the agent's income is not proportional.

2, free ip agents, there are many free ip agents, so why are there so many free crawler agents? Since it is free, there is no need to spend money. IP is of low availability, unstable, slow, frequently dropped, and 80% of IP is unavailable, which requires a lot of time and effort to test and select. Although it is a free ip agent, it costs a lot of expensive time and cost, and its efficiency is very low, which brings some trouble to our crawler workers. If it is an enterprise user who crawls a large amount of website data, it needs some consideration.

3. Charge ip agent, this kind of ip agent is charged, but the cost of self-built server is relatively low, which saves a lot of time and energy.
