DRF Serializer .errors not returning 'Enter a valid IPv4 address.' on invalid IP entry

Question

I have a django model defined with an IPAddressField:

class ExampleModel(models.Model):
    ip = models.IPAddressField('An IP Address')

For my API, I have defined a HyperlinkedModelSerializer for this model that operates in coordination with a ViewSet as excepted. However, when testing create actions against my API, I don't receive all the errors that I would typically expect a validated Django Form to return. Specifically, if I leave the 'ip' field empty, I receive an error as I would expect:

{'ip': [u'This field is required.']}

But, if I POST a request with an invalid ip address such as:

{'ip': '10.3.'}

I would expect serializer.errors to contain an error akin to what a Django Forms validator does, which is:

{'ip': [u'Enter a valid IPv4 address.']}

Any thoughts, suggestions, or clarifications on the matter? Am I blind to some obvious fact?

Further investigation shows that DRF has no IpAddressField, but django validators can be passed as args to serializer fields. As such, validating an IPV4 Address without adding one can be done as follows:

from django.core.validators import validate_ipv4_address
...
ip = serializers.CharField(validators=[validate_ipv4_address]
