Duplicated GenericIPAddressField validation errors with ModelSerializer and protocol

[HansAarneLiblik]

Hi!

I'm using GenericIPAddressField with explicit protocol as IPv4 (Also reproduces with IPv6) and ModelSerializer. If the input is not an valid IpAddress, DRF generates duplicate(ish) errors.

Repro

from django.db import models
from rest_framework.serializers import ModelSerializer


class A(models.Model):
    address = models.GenericIPAddressField(protocol="IPv4")  # Also reproduces with `IPv6`

    class Meta:
        app_label = "main"

class ASerializer(ModelSerializer[A]):
    class Meta:
        model = A
        fields = "__all__"


ser = ASerializer(data={'address': 'not an ip address'})
ser.is_valid(raise_exception=True)

Result

rest_framework.exceptions.ValidationError: {'address': [
    ErrorDetail(string='Enter a valid IPv4 address.', code='invalid'), 
    ErrorDetail(string='Enter a valid IPv4 or IPv6 address.', code='invalid')
]}

The second error message is incorrect

Thanks!
