NetSuite Customer Support will not provide you with a list of services or IP addresses for outbound communication from NetSuite.

For more information about alternatives to managing outbound access in NetSuite, see the following topics:

IP addresses for outbound communication from NetSuite are not documented in the NetSuite Help Center or in SuiteAnswers.

If you choose to use IP addresses to access or manage access to NetSuite services in firewall or proxy configuration, it is your responsibility to monitor for changes and update these settings when NetSuite IP address ranges change. If you decide to deploy a firewall, ensure that you have the resources to make it work in cloud environment.

Outbound HTTPS calls from NetSuite using SuiteScript 2.0: Improve the security of integrations and customizations that use the N/https Module for outbound HTTPS calls from NetSuite to a third-party server. Your integrations and customizations should use client certificates for outbound HTTPS calls. Client certificates ensure authenticity of the traffic source. See N/https/clientCertificate Module.

Access to an external SFTP server from NetSuite: See SSH Keys for SFTP. See also SFTP Authentication.

DNS Lookups: If you cannot take advantage of any of the previous options, advanced firewall tools can perform a lookup on the DNS record outboundips.netsuite.com and automatically grant access to requests from NetSuite. For outbound access, you can enter outboundips.netsuite.com as the fully qualified domain name (FQDN). You can use the FQDN, for example:

To permit NetSuite through your firewall to connect to your FTP servers.

To let a SuiteScript integration transmit data from NetSuite to an external system.

Email services: See Email Best Practices.

URLs for Account-Specific Domains

In cases where an application accesses more than one NetSuite account, you can use APIs for dynamic service discovery. See Dynamic Discovery of URLs.
