An allowlist lets your organisation limit access based on the IP address a user is accessing from. For example, you can allow access from only the IP address of your office network.
An Admin user can enable the IP allow list in the Security section of the organisation settings.
Enter the IP address your wish to restrict access for. The addresses/ranges must be specified using CIDR (Classless Inter-Domain Routing) notation.
Any changes may take 10-15 minutes to take effect.
