How to Best Store IPv6-Compatible Addresses in a Relational Database?

Storing IPv6-Compatible Addresses in a Relational Database

Storing IPv6 addresses in a relational database presents challenges due to its 128-bit length. Exploring various approaches to accommodate these addresses, the following options are considered:

2xBIGINT

Two UNSIGNED BIGINT columns can be utilized to store the address, providing a natural split at the /64 netblock boundary.

CHAR(16)

A CHAR(16) column allows for binary storage, directly storing the IPv6 address as a hex string.

CHAR(39)

Storing the address as a text string in a CHAR(39) column is an alternative, providing more flexibility for special scenarios.

8xSMALLINT in a Dedicated Table

Dividing the address into eight 16-bit fragments and storing them in a dedicated table allows for easier aggregation and manipulation of smaller address segments.

Recommendation

Selecting the most suitable approach depends on specific requirements. For the given scenario, storing the address using 2xBIGINT UNSIGNED columns is a viable solution. It aligns well with the /64 netblock boundary, maximizing storage efficiency and simplifying operations.
