Contact your security team to allowlist these Notion IP addresses or domains.

These can't be managed in your Notion account, so please contact your security team to allowlist these IP addresses or domains.

Notion is hosted on CloudFlare, so we recommend allowlisting
Cloudflare IP addresses.
The IP range you need depends on which way the connection goes.
- When Notion AI connects to a server you host: If your server limits incoming connections by IP address, allow the full 131.149.232.0/21 range as a source IP range. A regional subnet or the narrower 208.103.161.0/24 range may not be enough to allow all connections.
- When you connect to Notion from your company's network: Allow 208.103.161.0/24.
