  1. NAPTR Record Manipulation

  2. Introduction • Designing and implementing a mechanism to manipulate NAPTR records requires good understanding about the environment in which NAPTR lives • NAPTR Records are not lonely entities, they depend on and interact with external entities • The goal is to create a business model for ENUM and not build another DNS editing tool

  17. NAPTR Record Manipulation • In the context of ENUM, NAPTR records must evolve from simple DNS records into manageableentities that interact in a logical way with people and machines • The software that manipulates NAPTR records should contain triggers and have mechanisms to exchange data with the NAPTR Environment • Separate interface and functionality for ENUM Providers and ENUM Subscribers

  18. NAPTR Record Manipulation • ENUM Provider perspective • ENUM Subscriber perspective • ENUM Developer task list

  19. ENUM Provider perspective • Access to all NAPTR fields (advanced mode) • Access from Helpdesk with multiple operators • Changes should be performed real time • Syntax checks based on RFCs must be combined with logic checks • Changes of NAPTR records with version control • Changes can be rolled-back at a later time • ENUM numbers should not be mapped to meaningful names. Aliases should be used

  20. ENUM Subscriber perspective • User friendly interface for subscribers to reach their goal (number portability, plug and play communication) • Record changes committed in real time and not committed in batches • Version control and roll-back based on Provider policy or legal constrains • Subscriber awareness of the privacy issues related to populating DNS with contact details • Subscribers should not be able to add/remove themselves from ENUM (validation process)

  21. ENUM Developer task list • Provision IN platforms • Provision DNS zones • Manipulate NAPTR records • Provision VoIP accounts • Provision Billing systems • Generate usage information • Domain Registration • Logging, version control, roll-back • Validation
