Enum Constant Detail

• IPV4_ONLY

  public static final IPMode IPV4_ONLY

  IPv4 addresses only.

  Only IPv4 database files are downloaded and used. IPv6 lookups will return NOT_SUPPORTED status.

• IPV4_AND_IPV6

  public static final IPMode IPV4_AND_IPV6

  Both IPv4 and IPv6 addresses.

  Both IPv4 and IPv6 database files are downloaded and used. This roughly doubles the disk and memory requirements.
