What is the best method through which you can collect large volumes of data from a website? Web scraping is the answer for you! This is the method by which the scraping bots automate the human activity and basically scrape through the entire page to look for relevant information.
This is an efficient process and it also saves a lot of time! Owing to the fact that this technique is able to fetch data online in the quickest possible ways, this is a widely accepted idea.
How Is Web Scraping Blocked?
Although web scraping is convenient and all, it has its share of limitations too. Most websites are not very comfortable with the idea of data scraping from their pages. It eats their bandwidth, and might also infringe their copyrights. This is why web scraping is often blocked, and considered illegal, if not done ethically.
This means that the moment you start scraping the pages, the website understands that a human is not at work, and immediately blocks out the process. Quite often, this is understood by the speed of web scraping. The automated solution would, of course, be faster than manual human work. This is how web scraping businesses are being blocked by target servers.
So, is there a solution to this? How can you smoothly scrape a website without getting your servers blocked? Rotating your IPs can do the trick here! This is your best guess against the blocked data sources, in order to completely scrape the webpage data.
But in order to understand how IP rotation helps your cause, we would first have to understand how this works and what the underlying concept is.
Solution – IP rotation!
The process of IP rotation, first and foremost, requires an IP rotation software. It starts with a list of assigned IP addresses. Initially, these addresses are distributed or assigned to different devices, in an absolutely random manner. This could also be done at scheduled intervals such that the distribution is random.
Now, the next question is, who distributes this? This is either done by an administrator or by an IP rotation software. That is the basic idea of how IP rotation work.
So, how to rotate IP address? Whenever you are connected to the internet, you are working via an Internal Service Provider. This body then assigns an IP address to your computer. As long as your internet session is active, this IP address will be maintained. However, the moment you disconnect from this session and reconnect again, another fresh IP will be assigned to you and the previous one is discarded. In other words, the next available IP will be provided to this system. To put it in simple words, the IP is being rotated on a regular basis.
What happens in the background? The internet service provider has a list of IP addresses to assign from. But, there are always more users than the number of addresses. Thus, when a system disconnects from the internet network, the used IP is brought back to being an active member of the IP address pool. The next time when another system requires a fresh IP, this particular address could be assigned from the pool. This is how IP rotation is handled in the backend of the ISP.
Proxy Rotation Helps
In the virtual world of the internet, there are a number of different concepts arising out of IP rotation. For instance, the users tend to rotate proxy IP addresses, instead of the original ones. That means, the system can pick out any address from a proxy pool. As a result, businesses are able to operate with multiple IP addresses. How does this help? You would be able to manage different connections from one single system.
Using multiple rotating IPs means that the web page would not be able to track the scraping procedure being undertaken. This is because using many IP addresses indicates that there are multiple users scanning through the pages instead of a single automated process going on. This is the main difference.
Should You Invest In IP Rotation?
Ideally, when web scraping is blocked by the website’s operations, IP rotation proves to be the most effective solution. For every business dealing with web scraping, IP rotation and similar measures should be on the top of the priority list. Since this method imitates user behavior, it has the power to bypass all sorts of scraping restrictions. Thus, all measures to block the scraping of website content can be done with, with the help of the IP rotation techniques.
