How specific do I need to be on my mileage log?

I am self employed through instacart and am keeping track of a mileage log so that I can deduct some miles. I've been using the MileIQ app, but when I view the mileage report, it only shows the city names for my point of origin and destination. It does not show the specific address. Would this be sufficient for the IRS in case I ever get audited? Or would they want me to have a more specific mileage log with complete addresses rather than city names?
