order - The order of this NAPTR. Records with lower order are preferred.

preference - The preference, used to select between records at the same order.

flags - The control aspects of the NAPTRRecord.

service - The service or protocol available down the rewrite path.

regexp - The regular/substitution expression.

replacement - The domain-name to query for the next DNS resource record, depending on the value of the flags field.

Throws:
