Hurricane Electric (he.net) Setup#

Log in to https://dns.he.net
Ensure seams.so is added as a zone
Get your credentials:
- Username: Your he.net login username
- TOTP secret: If using 2FA, get from your authenticator app settings

Alternative: Using API Key#

If he.net supports API keys, you can also use:

{
  "hurricane": {
    "TYPE": "HURRICANE",
    "user": "your-username",
    "password": "your-password"
  }
}

Note: Keep creds.json private! It's gitignored by default.

Current Records#

From flyctl certs add seams.so:

A record: @ → 66.241.124.49
AAAA record: @ → 2a09:8280:1::b0:1269:0

These point seams.so to the Fly.io deployment.

Updating DNS#

When Fly.io IPs change:

# Get current IPs
flyctl ips list

# Update dnsconfig.js with new IPs
# Then apply:
cd dns/
dnscontrol preview  # Check changes
dnscontrol push     # Apply

Verification#

After applying DNS changes:

# Check DNS propagation
dig seams.so
dig AAAA seams.so

# Verify with external DNS
dig @8.8.8.8 seams.so

# Check SSL certificate status
flyctl certs check seams.so

# Test the site
curl -I https://seams.so/health
