When receiving an IPv6 there could be a "scope-id" part which is handled and validated by python stdlib.

However the string representation of this kind of value is not valid when used in postgres (see examples in RFC-4007 which raises an error

invalid input syntax for type inet: "fe80::1234%ne0"

Thus the db-prep value should not be the str representation of IPv6 addresses.

Internally django uses ipaddresse to validate IPv6 and uses a hack to remove the scope-id part:
