Domains and HTTPS
DNS Records and SSL for Makers
Learn the practical order for pointing a domain at a VPS, checking DNS, proving HTTP, and adding HTTPS.
Topic goal to ladder route
Know the destination, then climb the route.
A topic is the maker goal. A ladder is the route from what you understand now to one visible proof you can build, sketch, test, or explain. This one ties back to Deploy a Static Site on a VPS.
Connect a domain to a VPS without guessing whether the problem is DNS, Nginx, or TLS.
Read the short lesson, watch one source tutorial, sketch the idea, check the math, then practice.
Write the sequence you would use to connect a new domain to an existing VPS, including the command that proves each step.
Ladder steps
Each step should prove one idea before the project asks for the next one.
Point the root recordThe root domain usually needs an A record to the VPS IP. dig +short example.com A returns the expected IP.
Point www deliberatelywww can be a CNAME to the root domain or its own A record. dig +short www.example.com returns a sensible answer.
Serve HTTP firstCertificate issuance is easier after port 80 answers correctly. curl -I http://example.com returns the expected site.
Add HTTPS lastTLS should be configured after DNS and HTTP are already proven. curl -I https://example.com returns 200 or redirect as intended.
Examples to inspect
Use examples to read signals, not as blind recipes.
Check the root A record
Project signal
dig +short topicladder.com A
Expected signal: The VPS IPv4 address
Check the www answer
Project signal
dig +short www.topicladder.com
Expected signal: A CNAME or resolved IP
Verify public HTTP
Project signal
curl -I http://topicladder.com/
Expected signal: A status line and server headers
Common traps
- Changing DNS and TLS at the same time.
- Testing only from the VPS.
- Forgetting www when issuing certificates.
Practice task
Write the sequence you would use to connect a new domain to an existing VPS, including the command that proves each step.
Next steps
- Learn Nginx static roots.
- Learn release symlinks.
- Learn Search Console setup when the site is ready.
Practice path
- Near-Copy Rebuild: Recreate one example, decision path, or worked explanation from DNS Records and SSL for Makers. Keep most givens the same, then apply, explain, and check while naming each cue you used. Use the lesson's example block when it helps.
- One-Change Transfer: Change exactly one condition, number, input, symptom, material, or constraint from the near-copy case. Then apply, explain, and check again and explain what changed.
- Mixed Review Set: Interleave this topic with one prerequisite or adjacent idea. Write three short prompts: one recall, one application, and one comparison.
- Find And Fix The Error: Invent a plausible wrong answer, unsafe step, invalid assumption, or bad classification. Mark the first point where it goes wrong, then correct it using the lesson's check.
Flashcard preview
Why prove HTTP before HTTPS?
It narrows failures before certificate issuance and redirect rules add complexity.
What does the 'Point the root record' step prove?
The root domain usually needs an A record to the VPS IP. Check: dig +short example.com A returns the expected IP.
What does the 'Point www deliberately' step prove?
www can be a CNAME to the root domain or its own A record. Check: dig +short www.example.com returns a sensible answer.
What does the 'Serve HTTP first' step prove?
Certificate issuance is easier after port 80 answers correctly. Check: curl -I http://example.com returns the expected site.
What does the 'Add HTTPS last' step prove?
TLS should be configured after DNS and HTTP are already proven. Check: curl -I https://example.com returns 200 or redirect as intended.
When would you use `dig +short topicladder.com A`?
Use it to check the root a record. Expected signal: The VPS IPv4 address

Text lesson and video notes
This page works as a text lesson first. If you later watch a matching tutorial, use the notes pattern here to capture the build decision, timestamps, warnings, and the next practical task instead of saving a raw link.
Read the text lesson
Use the steps, examples, traps, and practice task on this page to understand the next move in a maker project.
Attach a video note
Save useful workshop or tutorial videos into an Obsidian note with timestamps, source links, and what each segment proves. The site does not need the video to be useful.
Review and practice
Download the cards, then finish the practice task before adding more links to your project notebook.
Source video for this ladder
Use the video as source material for notes, cards, and practice. The written ladder still works without playback.
Use the source as a companion, not as a replacement for the written ladder.
