[feature-request] Add an ISP in multiple pincodes

[atb00ker]

If a provider operates in multiple regions, say an entire city for most major cities of a country, it wouldn't be practical to add them one by one. Create a form for add an ISP in multiple pincodes, this form will save the data in a temporary place after I verify it, the data will move to the actual database.

P.S: Update the about page with the same change.
