Whitelist Guide for School IT
A one-page reference for school IT teams to allowlist ArielEd through web filters and firewalls.
Teachers: print or forward this page to your IT support team. It contains every domain, port and filter category they need to confirm before staff and students can use ArielEd.
Domains to allow
arieled.com*.arieled.com*.vercel.app(build previews — optional, only needed if you let staff test prereleases)
The above hostnames cover both the user-facing application and the API endpoints. ArielEd does not require any other outbound connection from the school network.
Ports
- 443 (HTTPS) — required
- 80 (HTTP) — redirects to HTTPS only; not required if your filter blocks plain HTTP
No other ports are needed. ArielEd does not use WebRTC, SMTP outbound from clients, or any non-standard port.
Web-filter categorisation
If arieled.comis being blocked as "Uncategorised", "Newly registered domain", or "AI / Generative AI", please request re-categorisation to "Education" or"Educational Tools" via your filter provider:
| Filter | Submission link |
|---|---|
| Smoothwall | https://smoothwall.com (contact support → URL categorisation) |
| LightSpeed Systems | https://www.lightspeedsystems.com/contact (URL re-categorisation) |
| Sophos / BrightCloud / Webroot | https://www.brightcloud.com/tools/url-ip-lookup.php |
| RM Education (Cleanly / SafetyNet) | Contact your RM account manager |
| NetSweeper | https://www.netsweeper.com (support portal) |
| Cisco Talos (Umbrella) | https://talosintelligence.com/reputation_center |
| Cyren | https://www.cyren.com (URL re-cat form) |
| Forcepoint | https://www.forcepoint.com (URL categorisation review) |
| Securly | https://www.securly.com (support → URL categorisation) |
Categorisation usually takes 1–5 working days after submission.
If you need to test access
To verify the school can reach ArielEd, open this URL on a school device: https://arieled.com. If it loads without a filter block-page, the site is accessible.
If you get a block-page, please screenshot it and email it to [email protected] — we can help diagnose which filter and category is causing the block.
Email allowlist
ArielEd sends transactional email (account confirmation, password resets, marking-complete notifications) from @arieled.com via Resend. To ensure these reach staff inboxes, please allow @arieled.comthrough your school's email filter (e.g. add to a safe-sender list in Microsoft Defender for Office 365 or Google Workspace).
SPF, DKIM and DMARC are configured on the sending domain.
