In the inevitable digital era, it is quite likely that you came across the term “rotating IPs.” However, when it comes to explaining what IP address rotation is and the cause it serves, it might become a challenge. To fully understand the purpose of this practice, let’s see what IP rotating is and what it is used for.
What is IP address rotation?
First, let’s visit the basics: What is an IP address?
IP address identifies every device connected to the internet, just like our physical addresses identifies where the letters, parcels and other goods should be delivered. There are two types of IP addresses: IPv4 and IPv6.
IP rotation is a process where assigned IP addresses are distributed to a device at random or at scheduled intervals.
For example, when a connection is active via an Internet Service Provider (ISP), an IP address is automatically attached from a pool of IPs. As soon as a disconnection and reconnection occur, the ISP will distribute the next available IP address.
ISP rotate IP address because they usually have more users than IP addresses at their disposal. Hence, when a particular user disconnects, the ISP will bring back the user’s most recently used IP address to their pool of IP addresses, thus ensuring the optimization of existing resources.
What is a proxy rotation?
ISPs rotate IP addresses, and this process is transparent to their users. However, out there in the online world, there are plenty of cases when internet users intentionally rotate their IP address. In fact, not even an IP address, but they rotate proxies, which allows them to operate under multiple different IP addresses.
If the proxy server is accurately configured, rotating IP addresses from a proxy pool of IP addresses is possible. With rotating proxies, you can manage numerous connections from a single device, and carrying out web crawling and data scraping operations becomes a much easier task.
There are different methods used to rotate IP addresses. In some cases it has to be done manually, as is the case with Chrome proxies (learn how to use proxy in Chrome). But here at Oxylabs, we offer a Proxy Rotator that does all the work for you. How does it work? A client gets one entry node (with the necessary amount of static proxies inside) which is used as a static address in order to get a proxy from the list. The rest is pure magic on our side! The rotator works by random IPs method, meaning it rotates an IP on each request.
What is a rotating proxy?
Rotating proxies is a process of assigning a new proxy with every request sent to the target. A rotating proxy itself is an IP address that is changed with another IP address when required.
Why rotate proxies?
First and foremost, proxy rotation enhances the level of anonymity. Secondly, as already mentioned, it is a widely used practice to automate such tasks as data scraping and web crawling in order to increase success rates.
When it comes to web scraping operations, a common challenge faced by many is avoiding getting blocked by websites while trying to gather the data.
Several techniques can aid the prevention of blocks, and one of them is proxy rotation. It can help to operate scrapers past most of the anti-scraping measures as it allows to imitate the behavior of multiple organic users. Hence, strengthening the chance of being undetected while gathering vast amounts of data.
There are countless cases out there when proxy rotation is being used. Here are some examples:
- SEO firms use proxies that automatically rotate to check keyword rankings from various locations or to promote specific content on social media accounts. I.e. with Brazil proxy or Germany proxy you can check keyword rankings in that country.
- Data intelligence companies rotate proxies automatically to scrape websites for analytics and performance purposes.
Methods used to rotate IP addresses
With our Datacenter Proxies, a proxy rotator can aid in this procedure. If you are looking for a way to change your IP address continuously, our proxy rotator is a perfect solution. Our residential proxies do not need a proxy rotator and are self-rotating.
However, if you are proxies by other providers you may need a tech person on your team. This person would have to correctly configure the proxy server, automate IP rotation and monitor the procedure.
Now you know what benefits a combination of proxies and IP rotation provide, and the purpose it serves. If you are indeed carrying out data scraping and web crawling tasks, we highly recommend implementing a high-quality proxy rotation solution to increase your success rates and protect your proxy pool infrastructure.
People also ask
Why is it essential to rotate proxies?
Websites employ various anti-scraping measures to block bot-like activity. Rotating proxies are essential to imitate organic user behavior in order to operate undetected on websites.
What are the most common mistakes with proxies and IP rotation?
The most common mistake comes from incorrectly configuring the process itself, and consequently overusing particular proxies, leading to bans due to bot-like activity.
Does a rotating proxy provide higher success rates when it comes to web scraping?
Yes. With correct proxy rotation, you can bypass restrictions and implement your web scraping project ideas without issues.
