Multiple, random DNS lookups for assets from the same subdomain

I was checking load performance of a website, and could see there are multiple DNS lookups for the assets even if its all hosted in the same subdomain. Also this is random, one asset might have DNS lookup in one load, but it might not have in another. (Attaching screenshots of the network tab)

What would be the cause of this behavior and how to fix this?

Load 1 Network Request 1

Load 2 Network Request 2

I don't think DevTools will give you the information you need to debug this. I think you'll need to dig into Chrome's internal tools. NetLog looks relevant.

This blog post also looks relevant: Google Chrome and (weird) DNS requests

If you do find an answer please ping me in the comments. There may be some information that we should be exposing in DevTools that we're currently not.
