Configuring IP Address Restrictions

IP address restrictions are used to limit access to Kintone to just your corporate network, and deny access from external sources. However, users cannot access Kintone when their IP addresses change on occasions such as using smartphones on a mobile network. We recommend the following settings based on your usage:

  • Users do not access the service using random IP addresses from their devices such as smartphones (the global IP addresses used to access the service are fixed)
    Select Allow specific IP addresses on IP Address Restrictions and enter the IP addresses you permit access.
  • Users access the service using random IP addresses from their devices such as smartphones
    Leave the default as Allow all on IP Address Restrictions and let users to activate Two-Factor Authentication setting. For details, see "Configure Two-Factor Authentication".

To configure IP address restrictions, specify the "global IP address" of the network that is allowed to access Kintone. For the global IP address of your network, contact your network administrator or Internet service provider. You can specify multiple global IP addresses.

IP address restrictions are offered at no additional charge. The following administrators are allowed to configure the restrictions:

  • Kintone Users & System Administrator

For details, see "Types of Administrators".


You can use Kintone Users & System Administration to configure IP address restrictions.

  1. On the "Kintone Users & System Administration" page, under "System Administration", click "Access Control".
    By default, Allow all is selected. Image of selecting access control
  2. Click Allow specific IP addresses.
  3. Specify all global IP addresses of the network that you want to allow. "CIDR" must be filled in only when you want to specify a range of IP addresses. IP addresses can be added or edited later. Image of IP address field
  4. Click "Save". It may take some time until the settings are applied.
    Once the configuration completes, an e-mail is sent to the e-mail address of the administrator.
