ENUM WG

• Possible Future Directions
• DNSSEC
• Provisioning
• NAPTR management/DNS content control
• Name server setup

2
DNSSEC issues for ENUM

• NOT DNSSEC protocol goop!
• NOT Political stuff like who owns a key
• Best common practices for stuff like
• Signing policies
• Key lengths, signature expiry times
• Howto for key rollover and/or key management
• Scaling optimal size for signing
• Signed and unsigned parts of the tree?
• What does this mean for ENUM clients?

3
Provisioning Issues

• Likely telco involvement in registrations
• e.g. Number cancellation or portability
• Telco says this number is not valid anymore
• May be helpful to have a standard way for a telco
  to express this
• EPP Schema?
• Information flow
• To registry? To Registrar? To Registrant?
• Some or all of these?

4
DNS Content Management

• Fine-grained control of NAPTR order preference
  fields
• BCP on how applications should update the DNS?
• Is it OK to mess with order preference of
  existing NAPTRs?
• What should DNS provider to if it encounters a
  conflict?

5
Name Server Setup

• Have an explicit document from the WG
  recommending how name servers for ENUM should be
  set up?
• Redundancy, no SPoFs
• Recursion disabled
• Minimal services on name servers
• Essentially smashing RFC2870 RFC2182
