### Hashing
Segment automatically hashes personally identifiable information (PII). This simplifies implementation for teams with data privacy requirements and eliminates issues with double-hashing that can result in failed matching at destinations.

Segment supports these 2 types of data for hashing:
* **Plain text data:** When you send plain text values to destinations that require hashed values, Segment automatically normalizes and hashes these values.
* **Pre-hashed data:** If you already hash your data before sending it to Segment, Segment is able to detect that the data is hashed, and will pass your pre-hashed data directly to the destination, avoiding double-hashing.

Or maybe "Manual hashing tips"?

> If you choose to hash data yourself, ensure you follow each destination's specific hashing requirements. Fields that support automatic hashing detection will display a tooltip indicating *"If not hashed, Segment will hash this value."*

For destination-specific hashing requirements, refer to the destination's API documentation.

## IP Allowlisting

IP Allowlisting uses a NAT gateway to route traffic from Segment's servers to your destination through a limited range of IP addresses, which can prevent malicious actors from establishing TCP and UDP connections with your integrations.
