The browser integration of troubleshooting.tools allows to use the browser address bar as a search input field, when needed, without visiting the original web page before.

This function is called OpenSearch and works with Apple Safari, Microsoft Edge, Mozilla Firefox and Google Chrome. Before we can start using it, we have to setup our browser for this function. Here an example for Google Chrome:

At the top right, click More and then Settings.

Under "Search engine," click Manage search engines.

To the right of "Other search engines," click Add.

Fill out the text fields as shown below and click Add.

Search engine:
Enter troubleshooting.tools or a name of your choice.

Keyword:
Enter the character "t" or a keyword of your choice, to trigger later the search function.

URL with %s in place of query:
https://troubleshooting.tools/lookup/ip/%s

The setup is complete. You are still able to continue to enter a URL in the address bar or any search terms that trigger a Google search.

The new feature is, if you enter an "t" followed by a space, then you activate the troubleshooting.tools search.

This cause that Google Chrome address bar react like the search field on this website.

To integrate the search bar into a different web page a few line are needed. The look and feel can be adjusted as desired.

<form method="post" action="https://troubleshooting.tools/lookup/ip/">
  <input type="text" name="IPADDRESS" placeholder="">
  <input type="submit" value="&#128269;">
</form>
