What is a Browser Lookup?

Browser Lookup can help identify the client browser, operating system, Device, and IP address information using the browser user agent. The web server uses user agent information to serve content to clients in a particular way, based on their browser type and operating system.

Browser User Agent (also called a user agent string) describes the type of browser used to view a site. The User-Agent string identifies the User Agent (UA) software on an HTTP request/response exchange. The information contained in a user agent includes:

• The Name of the Browser
• Browser Version Number
• Browser Rendering engine
• Other details about the specific client operating software

User-Agents also play an essential role in developing search engines, as they provide information about the browser and operating system used by a user to search engines, which can adjust their results accordingly. User agents are specialized programs that run in the background on most modern web browsers.

The primary purpose of a user agent is to provide information to web servers about the browser (and its capabilities), including the Operating system and other software installed on the machine (such as plug-ins), Plug-in architecture details such as extension support (where available), Language settings for use in language switching (where available), and Browser display characteristics such as screen resolution and color depth.

Modifying The User-Agent

Modifying your browser's user agent will usually be sufficient to deceive most websites into believing that you have used a different web browser than you are. User-agent inspection is the primary method used by websites to discover which site you're using. You can change the user agent information; however, it does not necessarily mean that all websites cannot detect it.

The user agents in different systems work differently:

• Mozilla/5.0 - Ignore this historical artifact from the days when new browsers on the marketplace forged their user agents
• Windows NT 10.0; Win64; x64 - Type of Windows operating system and Architecture
• Intel; Macintosh - Type of Hardware and Architecture
• Mac OS X 10.9s - System and type of the browser performing the request
• Gecko/20100101 - The Device's rendering engine
• Firefox/24 - The client's browser and edition
