Issue 2: Unique root
Why is a unique root used in ENUM?
- Say I have phone number +468971234
- I can choose between a.com and b.com
- I choose b.com, and get the DNS domain
- Axel is to call me
- He knows my phone number, +468971234, only
- How is he to know that it is in b.com and not a.com I have my data?
