DNS Setup Instructions for hcyberphysical.com

Current Situation

Squarespace DNS doesn’t support A records for apex domains
You have www.hcyberphysical.com working with CNAME

Solution: Use Cloudflare (Free) for DNS Management

Step 1: Create Cloudflare Account

Go to https://cloudflare.com and sign up (free)
Add your domain: hcyberphysical.com
Cloudflare will scan your current DNS records

Step 2: Configure DNS in Cloudflare

Once your domain is added, configure these DNS records:

For hcyberphysical.com (apex domain) - Add 4 A records:

Type: A
Name: @ (or hcyberphysical.com)
IPv4 address: 185.199.108.153
Proxy status: DNS only (gray cloud, not orange)
TTL: Auto

Repeat for these IPs (create 4 separate A records):

185.199.109.153
185.199.110.153
185.199.111.153

For www.hcyberphysical.com - Add CNAME:

Type: CNAME
Name: www
Target: hcyberphysical.github.io
Proxy status: DNS only (gray cloud)
TTL: Auto

Step 3: Update Nameservers at Squarespace

In Cloudflare, go to your domain overview
Copy the two nameservers Cloudflare provides (e.g., alice.ns.cloudflare.com and bob.ns.cloudflare.com)
Go to Squarespace domain settings
Update nameservers to point to Cloudflare’s nameservers
Wait 24-48 hours for DNS propagation

Step 4: Verify in GitHub

Go to: https://github.com/hcyberphysical/hcyberphysical.github.io/settings/pages
Under “Custom domain”, you should see hcyberphysical.com
GitHub will automatically provision SSL certificate

Alternative: Use Only www Subdomain

If you prefer to keep Squarespace DNS:

Your site will work at: https://www.hcyberphysical.com
https://hcyberphysical.com won’t work (unless Squarespace adds redirect)
Update CNAME file to: www.hcyberphysical.com

For Other Domains (.org and .net)

Set up redirects at your domain registrar to point to:

https://hcyberphysical.com
