Defining the scope of the cc. NSO Bart Boswinkel, Shanghai ICANN Meetings

A functional DNS model l l 2 Function 1: Registering data (DRF) Function 2: Run a name server and keep it running (NSF) The two functions are linked by generating a zone file At every level of the DNS these functions have to performed Bart Boswinkel, Shanghai ICANN Meetings 9/2/2021

Closer look at DRF l l New entries in the database Change of existing entries e. g. – – – 3 Change of technical data Transfer Cancellation Bart Boswinkel, Shanghai ICANN Meetings 9/2/2021

Closer look at NSF l l NS function is to ensure interoperability and stability of the DNS To achieve this – – Best current technical practices as described in RFCs and auxiliary documents Maintain resilience by e. g. l l – 4 Preventing single point of failure Automatic recovery of failures etc. Using up to date and appropriate technology Bart Boswinkel, Shanghai ICANN Meetings 9/2/2021

Model for the DNS from a cc. TLD perspective l DNS is hierarchical – – – l 5 First level or the ROOT Second level or the cc. TLD Third and lower or level user Distribution of responsibilities Bart Boswinkel, Shanghai ICANN Meetings 9/2/2021

Distribution of responsibilities l l 6 Vertical distribution Horizontal distribution Bart Boswinkel, Shanghai ICANN Meetings 9/2/2021

Vertical distribution l Responsibilities level 1 – – l Responsibilities level 2 (cc. TLD dbase/NS) – – l Data registration function (cc. TLD dbase) Name server function (cc. TLD NS) Responsibilities level 3 – – 7 Data registration function (IANA dbase) Name server function (ROOT) Data registration function (domain name data) Name server function (domain name NS) Bart Boswinkel, Shanghai ICANN Meetings 9/2/2021

Horizontal distribution l l l 8 Policy role: meaning the ability and power to define a policy Executive role: meaning the ability and power to act upon and implement the policy; and Accountability role: meaning the ability and power to hold the responsible entity accountable for exercising its power Bart Boswinkel, Shanghai ICANN Meetings 9/2/2021

Defining the scope of the cc. NSO l cc. NSO policy role in – – 9 Level 1 data registration function (IANA dbase) Level 1+2 name server function (ROOT server and cc. TLD NS) Bart Boswinkel, Shanghai ICANN Meetings 9/2/2021

Framework for Analyses l l Combining these two perspectives, policy and functions, the following framework emerges The framework presented offers the possibility to – – Delineate and identify specific policy areas; Identify and define roles with regard to these specific policy areas. NB. the delineation of the specific policy areas one has to be aware of the trade off between precision/granularity and practical use. 10 Bart Boswinkel, Shanghai ICANN Meetings 9/2/2021
