1 © 2002-2004 ag-projects.com NAPTR Record Manipulation

2 © 2002-2004 ag-projects.com 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 Introduction

17 © 2002-2004 ag-projects.com In the context of ENUM, NAPTR records must evolve from simple DNS records into manageable entities 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 NAPTR Record Manipulation

18 © 2002-2004 ag-projects.com ENUM Provider perspective ENUM Subscriber perspective ENUM Developer task list NAPTR Record Manipulation

19 © 2002-2004 ag-projects.com 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 © 2002-2004 ag-projects.com 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)
