Sharing some ideas about Chapter 1

[smf8]

Hi, Thank you for the great tutorial.

I started with Chapter 1 and had some questions that I think would be great to address in the original tutorial.

1. It's already mentioned that Question Section usually contains a single question. I think it's better to add the correlation with QDCOUNT (noting in the description that the value is usually 1).
2. Since most of the time the Question section contains only a single record, and considering that the compression is addressed for the Record section in the original RFC. I think it might help to mention this in the tutorial. Also, I couldn't produce a DNS query with multiple Questions to test compression using dig. So I think It's just introducing a complexity in a place that doesn't require it.
3. BTW adding the original RFC link would be great.

What do you think?
