Publishing a VM Website Without A/CNAME Records

If you want to make your VM-hosted website accessible without setting up traditional DNS records (A or CNAME), here are several alternative approaches:

1. Use IP Address Directly

Simply share your VM's public IP address (e.g., http://203.0.113.45)
Works immediately but isn't user-friendly
Add the port if not using 80/443 (e.g., http://203.0.113.45:8080)

2. Hosts File Modification

Edit the hosts file (/etc/hosts on Linux/Mac, C:\Windows\System32\drivers\etc\hosts on Windows)
Add a line like: 203.0.113.45 yourdomain.com
Only works for your local machine (not for public access)

3. Dynamic DNS Services

Use free services like No-IP, DuckDNS, or Afraid.org
They provide subdomains (e.g., yoursite.ddns.net) that update automatically when your IP changes
Often requires a small client running on your VM

4. Local Network Solutions

For internal networks only, set up a local DNS server
Or use mDNS (Bonjour/Avahi) with .local addresses (e.g., http://yourvm.local)

5. Port Forwarding with URL Parameters

Some services allow accessing via their domain with parameters
Example: http://example-proxy.com/?target=203.0.113.45:80

6. Cloudflare Tunnels (Argo)

Install cloudflared on your VM
Creates a tunnel that bypasses traditional DNS
Provides a *.trycloudflare.com URL

7. ngrok/Localtunnel Alternatives

Services that provide temporary public URLs:
```
  ngrok http 80
  localtunnel --port 80
```
Gives you a URL like https://random-subdomain.ngrok.io

Important Considerations

Without proper DNS, SSL certificates will be harder to configure
Many methods won't work for production/public-facing sites
Some ISPs block standard web ports (80/443) for residential connections

I hope this above information helps, if not, feel free to reply this post.

Publishing a website hosted on a Virtual Machine (VM) without setting up A or CNAME records typically means:

You want the site to be accessible without using a custom domain (like example.com).
Or you're okay with using an IP address or a temporary domain/subdomain.

Here are a few options, depending on your needs:

✅ Option 1: Use the Public IP Address of the VM

If your VM has a public IP address (like 123.45.67.89), you can access the website directly:

http://123.45.67.89/

If you've set up a web server (like Apache, Nginx, etc.) on the VM and it's serving files properly, your site will be live.

⚠️ You won't need DNS records, but:
- This isn’t user-friendly.
- No SSL (HTTPS) unless you use a self-signed certificate or a reverse proxy like Cloudflare Tunnel (see below).

✅ Option 2: Use a Dynamic DNS Provider (No A/CNAME Needed)

Some dynamic DNS services give you a subdomain (like yourname.dyndns.org) and handle the DNS for you.

Examples:

Most of them work without needing you to modify A/CNAME records manually. They may require a script on your VM to update IP addresses.

✅ Option 3: Use Cloudflare Tunnel (Zero Trust)

Cloudflare Tunnel allows you to expose your local or VM-hosted site to the internet without opening ports or using DNS.

Free tier available
Works even if your VM has a private IP
You get a temporary Cloudflare domain like yourname.trycloudflare.com

Steps:

Install Cloudflare Tunnel (cloudflared) on your VM.

Run:

   cloudflared tunnel --url http://localhost:80

You’ll get a public URL you can share.

👉 Great for temporary or secure testing.

✅ Option 4: Use Hosting Provider's Temporary Domain

If you're using a cloud provider like:

DigitalOcean
Linode
AWS EC2 (with public DNS like ec2-12-34-56-78.compute-1.amazonaws.com)

They often give you a public DNS address by default that you can use without configuring anything.

Example:

http://ec2-12-34-56-78.compute-1.amazonaws.com/
