INET

The INET data type in SQL is used to store IPv4 and IPv6 addresses. These addresses can be compared, filtered, and sorted using standard SQL operations.

Here's an example of how to create a table, insert data, and query data using the INET data type:

Creating a table with an INET column​

To create a table with an INET column, use the following SQL syntax:

CREATE TABLE computer (ip INET);

Inserting data into the INET column​

To insert data into the INET column, provide the IP addresses as strings or integers:

INSERT INTO computer VALUES
    ('::1'),
    ('127.0.0.1'),
    ('0.0.0.0'),
    (4294967295),
    (9876543210);

Querying data from the INET column​

To query data from the INET column, use standard SQL syntax:

SELECT * FROM computer;

This query will return the following result:

ip
-----------------
::1
127.0.0.1
0.0.0.0
255.255.255.255
::2:4cb0:16ea

Filtering data using the INET column​

You can filter data using the INET column with standard SQL operators:

SELECT * FROM computer WHERE ip > '127.0.0.1';

This query will return the following result:

ip
-----------------
::1
255.255.255.255
::2:4cb0:16ea

Querying for specific IP addresses​

To query for specific IP addresses, use the following syntax:

SELECT * FROM computer WHERE ip = '127.0.0.1';

This query will return the following result:

ip
---------
127.0.0.1
