2ip bot

2ip bot is a diagnostic web crawler operated by the web services company 2IP. It is designed to gather technical information about a website's infrastructure, such as its server configuration and the type of content management system (CMS) it uses. The data collected by the bot powers 2IP's suite of public web diagnostic tools and is not used for search engine indexing.

What is 2ip bot?

2ip bot is a specialized web crawler operated by 2IP, a service known for providing a variety of web diagnostic tools. The bot's primary function is to act as a diagnostic scanner, collecting technical data about websites, including their server configurations and content management systems (CMS). It identifies itself with user-agent strings such as 2ip bot/1.1 (+http://2ip.io) or 2ip.io cms detector/2.0, allowing website administrators to recognize its activity in server logs. Compared to crawlers from major search engines, 2ip bot has a smaller footprint, sending a limited number of requests at a low frequency. Its purpose is technical analysis rather than content indexing, making it a specialized utility.

Why is 2ip bot crawling my site?

The 2ip bot visits your website to collect technical details, not to index your content for search results. Its visit is often triggered when a user enters your website's address into one of 2IP's online diagnostic tools. The bot may also be performing a broader scan as part of 2IP's data collection efforts for its services. It primarily targets technical endpoints to gather information about your web infrastructure, such as what CMS you are using or to verify IP address information. While its visits are generally infrequent and not considered malicious, they are typically not explicitly requested by the website owner.

What is the purpose of 2ip bot?

The main purpose of 2ip bot is to power the suite of web diagnostic tools offered by 2IP on its platforms, 2ip.io and 2ip.ru. The data it collects allows developers and webmasters to analyze various technical aspects of websites. This information is used for several key functions, including identifying the content management systems (CMS) that websites use, analyzing server configurations and security settings, and supporting IP address verification services. The primary beneficiaries of the bot's activity are the users of 2IP's diagnostic tools, not the owners of the websites being crawled.

How do I block 2ip bot?

To block the 2ip bot from accessing your website, you can add a specific rule to your robots.txt file. This file gives instructions to web crawlers about which parts of your site they are allowed to access.

Add the following lines to your robots.txt file to prevent 2ip bot from crawling your site:

User-agent: 2ip bot
Disallow: /

How to verify the authenticity of the user-agent operated by 2IP?

Reverse IP lookup technique

To verify user-agent authenticity, you can use host linux command two times with the IP address of the requester.

```
> host IPAddressOfRequest
```
This command returns the reverse lookup hostname (e.g., 4.4.8.8.in-addr.arpa.).

> host ReverseDNSFromTheOutputOfFirstRequest

If the output matches the original IP address and the domain is associated with a trusted operator (e.g., 2IP), the user-agent can be considered legitimate.

IP list lookup technique

Some operators provide a public list of IP addresses used by their crawlers. This list can be cross-referenced to verify a user-agent's authenticity. However, both operators and website owners may find it challenging to maintain an up-to-date list, so use this method with caution and in conjunction with other verification techniques.
