DNS Process?

[dimpals]

What process does dns go through?

On an sniffer I got this:
DNS Request = 4432
DNS Correct Response = 1715
DNS Error Response = 1070

My Correct Response and Error Response dont add up. Why is that?

How does dns handshake/process work?

Those sniffer results don't make sense to me. What were you expecting, to have the error and correct responses match?

I usually look at the packet payloads when I use a sniffer, not those codes.

There isn't a unique DNS handshake, it uses the standard TCP handshake before the actual DNS dialogue starts.

Here's a breakdown on the larger process:
