QUESTION

Which encoding does application/dns-message use?

Asked 2021-Aug-05 at 14:35

I am writing DNS-over-HTTPS server which should resolve custom names, not just proxy them to some other DoH server, like Google's. I am having trouble properly decoding the body of the request.

For example, I get body of request, that is in binary format, specifically in javascript in Uint8 ArrayBuffer type. I am using the following code to get base64 format of the array:

As stated in the RFC:

Definition of the "application/dns-message" Media Type

The data payload for the "application/dns-message" media type is a single message of the DNS on-the-wire format defined in Section 4.2.1 of [RFC1035], which in turn refers to the full wire format defined in Section 4.1 of that RFC.

So what you get is exactly what is sent on the wire in the normal DNS over 53 case.

I would recommend you use a DNS library that should have a from_wire or similar method to which you can feed this content and get back some structured data.

Showing an example in Python with the content you gave:

QUESTION

What is the difference between DNS-over-HTTPS and DNSSEC?

Asked 2020-Sep-03 at 01:52

I was just introduced to the Domain Name System Security Extensions (DNSSEC) and it sounds very similar to the concept of DNS-over-HTTPS (DoH) and DNS-over-TLS: to add privacy and security into DNS lookups.

What are the main differences between these protocols? Do they compete/serve the same goals?

DNSSEC just signs answers, to check integrity and preserve DNS cache poisoning from unauthorized fake "servers". With DNSSEC, any eavesdropper can:

listen traffic
understand "this is DNS"
watch domain names for request/responses.

DOH is DNS over HTTPS. There is:

traffic encrypted
eavesdropper cannot understand - is this DNS or web http.
eavesdropper unable to see contains of requests/answers.

Advantage of DNSSEC - more quick. Advantage of DOH - more private.

Install DNS-over-HTTPS

Cross-Platform: DoH ASP.NET 5 Web App
Note: You can also run the DNS-over-HTTPS.exe to directly run the DoH console app with built in web server for quick testing. Create a config file for your domain name at /etc/nginx/sites-enabled/doh.example.com with the config shown below. Save the certificate and key files to path given as in the config. Reload nginx web server to finish the configuration. Note: You can also run dotnet DNS-over-HTTPS.dll command to directly run the DoH console app for quick testing. The DoH service is available on the /dns-query location on the web site that you are running. If you are running it directly as a console app then your DoH end point URL will be http://localhost:5000/dns-query. For Linux systemd daemon, the DoH end point will be http://localhost:8053/dns-query as per the argument provided in the systemd.service file.
Windows:
Download the doh-aspnetcore.zip zip file.
Edit the appsettings.json file in notepad to set the DNS server of your choice.
Install the DoH app on Windows IIS web server by creating a new website and extracting the doh-aspnetcore.zip zip file into the wwwroot folder of the website.
Configure SSL certificate on IIS for the website so that the service works over HTTPS.
Linux:
Download and extract doh-aspnetcore.zip zip file to /var/aspnetcore/doh
Edit the appsettings.json file in nano to set the DNS server of your choice.
Install the DoH app as a systemd daemon:
Make sure that the DoH daemon is running without issues by running:
Configure a reverse proxy using a web server like nginx that does the SSL termination for the DoH service. Install the nginx web server using:
