Validate IPv6 address format in PostgreSQL using regex operators. SQL examples for IPv6 address validation in Postgres.

The Regex Pattern

Regex pattern

Use this pattern with PostgreSQL's ~ operator.

PostgreSQL SQL Example

-- Use PostgreSQL regex operator to validate IPv6 address format in network logs or connection tracking tables
SELECT *
FROM your_table
WHERE your_column ~ '^([0-9a-fA-F]{0,4}:){2,7}[0-9a-fA-F]{0,4}$';

How This Works

Use PostgreSQL regex operator to validate IPv6 address format in network logs or connection tracking tables. The regex pattern is used with PostgreSQL's ~ operator to filter rows at the database level.

Using regex directly in SQL is efficient for use cases like data validation โ€” it avoids loading data into application memory just to filter it with a regex.
