The tool displays the string text your web browser sends in the «User-Agent» header in the HTTP requests. The User-Agent Information identifies your browser and operating system and their versions.
About User Agent Information Tool
In the back days, the internet was on a manual system based on commands. The user had to send the instructions to communicate. But since the evaluation of the internet, now the browsers do that job automatically.
Currently, there are more than 4.6 billion internet users in the world. From our mobile devices to our smart homes, we are always connected to the internet.
Without a browser, we cannot surf the internet. Browsers are the internet’s need, equipped with loads of security policies, server agreements, and connectivity codes to run ideally. Generally, when the browser wants to connect with any website’s server, it first sends the user-agent info to make the connection.
I bet you are now thinking, «what’s my user agent?» It’s an intermediary or middle man between you and the internet world. In simple words, it’s a string of text that is unique for each software or browser on the internet and holds the technical information about your device and operating system. User-agent is present in the HTTP headers when the browser wants to connect with the webserver.
Each bit of the user agent contains some detailed information. However, there is no standard way to write the user-agent. It varies from browser to browser. Some browsers stuff the user-agent header with a lot of information.
Once a connection between a browser and web server is established, the content negotiation begins. That lets the website serve its various versions depending upon the user-agent string. Once the user-agent passes its ID card to the web server, it provides the files, media, and scripts suitable for the particular user.
Figuring the user-agent string is not only helpful to us but also for the providers. It automatically sends the correct translation of certain documents based on the language preference of the user. You may have seen this when accessing websites with a different language that is automatically translated.
How to identify «What’s My User Agent» by using an online tool?
As we discussed earlier, there is no standard way to write the user-agent string. Therefore, dnchecker.org provides a tool to decode the user-agent string to figure out everything it’s saying.
Can I change or fake my user agent?
Yes, you can change your user agent, and that process is called user-agent spoofing. Sometimes, we need to test different things. For example, you are running a campaign for MAC OS, and you want to figure out that either the campaign is running correctly for MAC OS and not targeting the Linux users, changing the user-agent of the browser helps you in this regard.
Web developers usually daily change the user-agent to check the progress of their website’s behavior in different browsers and devices.
For switching the user agent, you can rely on a browser extension or you can use the developer console to manually change the user agent that your browser will send with its HTTP requests.
Suppose you are using the Chrome browser but changed your user-agent to Internet Explorer 11. If the website only focuses on the user agent and perceives the browser to be IE 11. However, if the website performs the extra checking measures like it had WebRTC enabled. Then the website will detect the browser which supports WebRTC.
Therefore, with extra measures, you can detect the actual browser. But usually, the websites do not take the checking to that level.

Description
User agents are used throughout client-server computing and application user agents that request web-based content are commonly browsers and search engine bots. Newsreaders, screen readers and other web-related applications and systems act as agents as well. In the case of a user requesting a web page with a browser, the browser transmits details about the user’s computer operating system as well as information about the browser itself. The user agent information is contained in the header portion of the request. The receiving server may choose to ignore the information in the user agent, or modify its response based on the information.
Web site developers frequently leverage information parsed from user agents to optimize the user experience based on the browser and device types. With the recent explosion of smartphones, many developers now check the device type and direct the user to a site optimized for mobile or use a mobile optimized style sheet. Some web sites check the browser version in the user agent to ensure the user has a current browser and directs them to various vendors’ web sites to download a newer version. Many enterprise applications check browser type and versions due mostly to heavy customization of the UI and to ensure an optimal experience. The user is typically denied access without the application’s “certified” browser or is notified the experience will be less than optimal.
Anatomy
When a user requests a web page or other resource, the request’s header portion contains the user agent and other information (see sample header below).
The breakdown of the user agent in the header is as follows:
What Is My User Agent?
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_8_0) AppleWebKit/536.3 (KHTML, like Gecko) Chrome/19.0.1063.0 Safari/536.3
The Internet has a ubiquitous presence in our highly digitalized world. From our smartphone to our smart homes, seemingly everything is connected to the internet. But did you know, you can’t just connect to the internet?
You need what we call as a ‘user agent’ to act as the middle person between you and the internet at large. I bet you’re thinking, “what is my user agent?”
As an intermediary between you and the internet, a User Agent is unique to every person on the internet and holds technical information about your device and software.
To understand this better, we must backtrack and understand how the web worked before and the benefits of user agents.
Back in the day, the internet was a manual system based on commands; users had to type instructions and send messages. Ever since the evolution of the internet, browsers do this job automatically. All we have to do is point and click – the rest is done by the browser that is acting as your agent and converts your commands into action.
So, when the browser provides you access to a website, it performs its duty as an agent when it retrieves the content for you. Alongside user agent identification, it also sends information such as the device and network it’s on to the browser.
User Agents
Internet browsers are straight up the perfect example of a user agent, but there are also other tools that act as one.
Ironically, not all user agents are controllable in real-time by us. For instance, search engine crawlers are also user agents but are in fact automated – the robots have the ability to trawl through the web without having a human control them. The perfect example of a crawler is Google images, Slurp, Yahoo and many more.
What Is My User Agent String?
Once the webserver and user agent are connected and the identification process has finished, then content negotiation begins. This lets the website serve numerous versions of it depending on the user’s agent string.
Once the user agent has passed its ID card to the server, it then provides a combination of files, media, and script which are suitable for the particular user. To answer the question ‘what is my user agent string?’ and in more detail, you could take a look at the example through our tool.
The results that you will witness will be unique and a different one will be generated on other computers and devices. Although a little complex, figuring out the user agent string is very useful not just to us, but the providers as well.
It automatically sends the correct translation of a certain document based on the language preferences of the user – you may have noticed this when accessing websites with a different language that is automatically translated.
It also helps you gather information about your website visitors and provides insights for improving your content.

Что такое User agent и как его изменить
Во время взаимодействия с браузером пользователь может встретить такое понятие, как User agent. Используется технология с таким названием во всех веб-обозревателях.
Далее я предлагаю узнать, что такое User agent, где он используется и какую пользу может принести обычному юзеру.
Понятие User agent
Начать необходимо с расшифровки самого понятия, чтобы сформировалось хотя бы поверхностное знание о нем. User agent – это программный элемент браузера, обозначающий человека, пользующимся им. Обычно он хранится в файле и содержит несколько текстовых строк, которые как раз и необходимы для идентификации. Действие агента пользователя происходит в сети от имени самого юзера, оно идентифицирует браузер и запрашивает доступ к страницам после отправки запроса на сервер.
Файл агента пользователя чаще всего включает в себя сведения о браузере, его версии, используемом устройстве, операционной системе и механизме веб-рендеринга. Разработка User agent позволила избавиться от проблемы, когда конкретные веб-страны могли обрабатывать только определенные браузеры, для которых они и разрабатывались.
Разновидности User Agent
Важно отметить, что каждый тип девайсов, будь то ПК, ноутбук, смартфон или планшет, может иметь своего агента пользователя, а далее все зависит уже от используемого ПО. User Agent идентифицируется:
Веб-обозревателями. Сюда входят все браузеры: Google Chrome, Яндекс.Браузер, Opera и другие.
Поисковыми системами. Яндекс, Google, Рамблер и все остальные поисковики тоже обращаются к веб-страницам, соответственно, имеют свой UA.
Игровыми консолями. Если вы запустили браузер или используете веб-элементы на своем Xbox или PS, устройство тоже выходит в сеть, а далее в дело вступает User Agent.
Мониторами ссылок. Есть специальные ресурсы, предназначенные для проверки ссылок, и, да, они тоже используют эту технологию.
Электронными книжками. Большинство современных моделей имеют на борту Wi-Fi, что позволяет запускать браузер, пускай и для выполнения минимальных задач.
Это список основных продуктов, использующих User Agent, которого вполне достаточно для понимания того, насколько широко используется данный программный механизм и насколько он упрощает взаимодействие с веб-страницами.
Как узнать и изменить User Agent
Чтобы узнать User Agent браузера во время использования ПК или мобильного устройства, не нужно искать какие-то файлы или изучать конфигурации, переходя на страницы по специальным ссылкам. Для выполнения поставленной задачи существуют специальные инструменты, встраиваемые в популярные онлайн-сервисы, которые занимаются сбором и предоставлением определенной информации. Например, известный сайт 2IP, который предназначен для проверки сетевого адреса пользователя, может вывести на экран и текущий User Agent.
Вам нужно только перейти на соответствующую страницу выбранного онлайн-сервиса и прокрутить ее немного вниз, если в первых строках нет необходимой информации. Кстати, если конфигурация браузера была изменена вручную специально для того, чтобы блокировать правильный UA, он не определится при помощи онлайн-сервиса.
Изменение User agent может потребоваться веб-дизайнерам, проверяющим работоспособность сайта на разных устройствах (не надо устанавливать кучу разных браузеров и использовать смартфоны с различными диагоналями – поставили плагин с подменой User agent и переключаетесь между доступными «устройствами»), и пользователям, желающим скрыть информацию о своем ПК и браузере, поскольку благодаря данному программному механизму происходит какой-никакой сбор информации.
Принцип изменения агента пользователя в разных веб-обозревателях отличается, но почти всегда универсальным методом будет использование User-Agent Switcher.
Установите это расширение, откройте главное меню и измените данные в строке на необходимые. Существуют и другие плагины такого рода, которые вы без проблем можете отыскать в магазине расширений используемого браузера.
Уточним, что для Chrome можно использовать более простой метод, связанный с изменением свойств объекта. Для этого щелкните правой кнопкой мышки по ярлыку, который вы используете для запуска программы, из контекстного меню перейдите в его свойства и в поле со ссылкой на объект добавьте:
В этой статье вы узнали, что User agent – крайне полезная функция, которая позволяет с комфортом использовать любые браузеры и другие средства просмотра веб-страниц, не задумываюсь о том, что какой-то сайт может не открыться из-за проблем с совместимостью или его внешний вид не адаптируется под используемое устройство.

About User Agent
User Agent
The User-Agent request header contains a characteristic string that allows the network protocol peers to identify the application type, OS, software vendor or software version of the requesting software User Agent. Armed with this information, you can develop richer and more dynamic websites that deliver different experiences based on the user agent that is visiting.
When your browser (or similar device) loads a website, it identifies itself as an agent when it retrieves the content you have requested. Along with that user agent identification, the browser sends a host of information about the device and network that it is on. This is a really set of data for web developers, since it allows them to customize the experience depending on the User-Agent that is loaded the page.
Can I change my user agent?
It is possible to change or «fake» what your web browser sends as its user agent. Some desktop/mobile web browsers will let you change what the browser identifies itself as (ie «Mobile Mode» or «Desktop Mode») in order to access certain websites that only allow desktop computers. If you change this setting, the user agent is what is affected.
