## Class InetAddressPoint

- All Implemented Interfaces:
    IndexableField

      public class InetAddressPoint
      extends Field

  An indexed 128-bit `InetAddress` field.

  Finding all documents within a range at search time is efficient. Multiple values for the same field in one document is allowed.

  This field defines static factory methods for creating common queries:

  - `newExactQuery(String, InetAddress)` for matching an exact network address.
  - `newPrefixQuery(String, InetAddress, int)` for matching a network based on CIDR prefix.
  - `newRangeQuery(String, InetAddress, InetAddress)` for matching arbitrary network address ranges.
  - `newSetQuery(String, InetAddress...)` for matching a set of network addresses.

  This field supports both IPv4 and IPv6 addresses: IPv4 addresses are converted to IPv4-Mapped IPv6 Addresses: indexing `1.2.3.4` is the same as indexing `::FFFF:1.2.3.4`.

    `PointValues`
