IP address fields

Provides a field type for storing single IP addresses or IP ranges, in either IPv4 or IPv6. Values are stored as a [start, end] pair in indexed binary columns, so range-membership queries run natively in SQL against the field's index rather than in PHP.

Accepted input

A single text field accepts any of these forms and normalises them to an internal [start, end] pair:

• A single IP — 10.10.10.10 or 2001:db8::1
• A dash range — 10.10.10.0 - 10.10.12.255 (whitespace ignored)
• A partial IPv4 range (last octet only) — 10.10.10.10-20 becomes 10.10.10.10-10.10.10.20
• Wildcards, any number of asterisks — 10.10.*.*, 2001:db8::*:*
• CIDR notation — 10.10.10.0/24, 2001:db8::/32

Invalid input is rejected inline by the widget, and as an HTTP 422 Unprocessable Entity response by the REST / JSON:API endpoints, with the offending input echoed back in the error message.

Per-field settings

• IP version — restrict to IPv4, IPv6, or allow both.
• Allow ranges — toggle whether the field accepts a range or only a single IP.
• Allowed range — optionally limit accepted values to a specific sub-range, configured independently per family.

Views integration

Field values are exposed to Views with native sort and filter handlers. The filter supports =, !=, <, <=, >, >=, BETWEEN, and NOT BETWEEN. Range-to-range comparisons are correct on both sides — e.g. "all entities whose stored range overlaps 10.0.0.0/8" is one filter operator, not a custom query.

Drupal 7 migration

The module ships a migrate field plugin that maps the D7 field_ipaddress field type onto the current storage. Old ip2long() BIGINT columns are converted to the current binary
representation; D7's convention of end = 0 meaning "single IP" is recognised and migrates cleanly.

For developers

A helper service, field_ipaddress.iptools, exposes the two query patterns the field is designed for without requiring callers to hand-roll the binary encoding:

$iptools = \Drupal::service('field_ipaddress.iptools');

  // Entities whose stored range contains a single IP.
  $nids = $iptools->containsIp('node', 'field_ip', \Drupal::request()->getClientIp());

  // Entities whose stored range overlaps a given range.
  $nids = $iptools->overlapsRange('node', 'field_ip', '10.0.0.0/24');
  

Both methods accept a string, an ip2long() integer, or a pre-parsed \Drupal\field_ipaddress\IpAddress object. Entity access checks are on by default.

Compatibility

Drupal 10, 11, and 12. On Drupal 10 / 11.0 / 11.1 the Views integration transparently falls back to the pre-11.2 procedural helper — no action required.
