Thanks a lot!

Thanks a lot, with the help of you project I've been able (after some trial & error) to write my own DNS server implementation - altough I've decided to do it in C# (because that's what I'm learning right now) and not in Rust (also, copy-paste Rust code seemed too easy).
You can check it out at https://github.com/delneg/dns_server_csharp
There are also branches for each chapter, if you're interested

Glad you found it useful. Looks like a nice project, so well done. :) I'll consider adding a section for ports to other languages, and link to it.

@EmilHernvall Really enjoying this guide, it's been a lot of fun. Any plans for others like this?

[EmilHernvall]

Maybe. :) There are some other protocols that I'd like to try, like DHCP and SMTP, but not sure when I'll get to that.

[Schachte]

Ooo SMTP would be great fun!

Adding my thanks, this guide was extremely helpful in implementing a custom dns server. I particularly liked the progressive breakdown

Just adding my thanks for this!
Started going through it, trying to build an ENUM (NAPTR records) server for Telephony purposes. This is being extremely helpful

Just a qq... I can see in the DnsHeader struct a boolean field called "checking_disabled" but I can't find anything in the RFC or the packet itself about it. What's its purpose?
