Bulk

There is also a page for bulk DNS queries. You need to upload a file in the format instructed on the page, here is an example file.

This uses the same method for making requests as the homepage, through axios. The format with which the results are saved is slightly different due to there being more requests.

Rendering

This uses conditional rendering and dynamic imports so the full page will only load when you upload a file

Table

This uses react-table for showing the data, the code for this is in the component components/table, so if you want to change the style of the table, you can do it here.

Bar Chart

There is also a bar chart provided by chart.js. For simplicity it uses a React wrapper react-chartjs-2 where the data can just be passed as props
