大家好！

下面是一个使用造假者填充模型的脚本。 Faker允许使用“ address_class”参数。指定address_class ='a'将其范围缩小，但仅缩小到10.0.0.0/8。如何进一步调整发电机，例如调整到10.10.10.0/24？

import os
import django
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "config.settings.local")
django.setup()
from workplace.models import IpAddress
import factory
import faker
from faker.providers import internet
faker = faker.Factory.create()


class IpAddressFactory(factory.django.DjangoModelFactory):
    class Meta:
        model = IpAddress
        django_get_or_create = ('ip_address',)
    ip_address = faker.ipv4_private(address_class='a')


ip = IpAddressFactory()
print(ip)

与其说是适当的解决方案，倒不如说是一种解决方法：

ipv4_private使用_IPv4Constants._private_networks中的类providers.internet

在_private_networks中调整class IPv4Constants可以解决问题

/lib/python3.7/site-packages/faker/providers/internet/ init .py`

class _IPv4Constants:
    """
    IPv4 network constants used to group networks into different categories.
    Structure derived from `ipaddress._IPv4Constants`.

    Excluded network list is updated to comply with current IANA list of
    private and reserved networks.
    """
    # Three common private networks from class A, B and CIDR
    # to generate private addresses from.
    _private_networks = [
        # ip_network('10.0.0.0/8'),
        # ip_network('172.16.0.0/12'),
        # ip_network('192.168.0.0/16'),
        ip_network('10.10.10.0/24'),

    ]

使用Django模型的factory_boy和faker生成特定子网的ipv4地址
