What is IP Whitelisting?

IP Whitelisting (also called IP allowlisting) is a security feature that restricts database access to only specific, pre-approved IP addresses. When enabled, your database will only accept connections from the IP addresses on your “whitelist” and block all other connection attempts. Think of it like a VIP guest list for your database - only the addresses you’ve specifically approved can enter.
If your database requires IP whitelisting and you don’t configure it properly, Julius will not be able to connect to your database, even with correct credentials.

​
Julius IP Address for Whitelisting

To allow Julius to connect to your database, you’ll need to whitelist our current IP address.

Get Current IP Address

Visit your Data Connectors settings to find the current Julius IP address for whitelisting. The IP address is automatically updated there when our infrastructure changes.
Always use the IP address shown in your Julius settings rather than any hardcoded values, as our infrastructure IP may change over time.

​

Common Issues and Solutions

​
Security Best Practices

​
Database-Level Security

  • Use read-only credentials when possible to prevent accidental data modification
  • Create dedicated Julius user with minimal required permissions
  • Regularly rotate passwords according to your security policy
  • Monitor connection logs for unusual activity

​
Network-Level Security

  • Use specific ports rather than opening broad port ranges
  • Combine with VPN if required by company policy
  • Regular security audits of firewall rules and access patterns
  • Document all external connections for compliance and audit purposes

​
Ongoing Maintenance

  • Check your Julius settings periodically for IP address updates
  • Test connections regularly to ensure continued functionality
  • Keep firewall rules organized with clear descriptions and regular cleanup
  • Coordinate with IT team for any infrastructure changes
Always test your data connector setup in a development environment first before configuring production database access.
