# The NFSN API does not return any internal "ID" strings for any DNS records.
# This means that we must set all returned Record objects' id properties to
# None. It also means that we cannot implement libcloud APIs that rely on
# record_id, such as get_record(). Instead, the NFSN-specific
# ex_get_records_by() method will return the desired Record objects.
# Additionally, the NFSN API does not provide ways to create, delete, or list
# all zones, so create_zone(), delete_zone(), and list_zones() are not
# implemented.
