class IPAddress(Collection):
    """IP address collection."""

    __collection__ = 'ip_addresses'
    _index = [
        {"type": "geo", "fields": ["geo_location"]}
    ]

    _key = String(required=True)  # the actual ip address
    ip_version = Integer(required=True, options=[4, 6])
    description = String(default='')
    geo_location = List(Float)
