Thanks, it is not standardization so far, but is a proposal way to solve the MNP(Mobile Nubmer Portability) issue, if every subscriber in one registry owned a separate zone file, it should easy realize number portability. Certainly there are any other soultion for the MNP topic.

I'm not an ENUM expert but I wonder where you've found that strange
rule. There is a *domain* for each E164 number but a *zone* per
number, no, I find it hard to believe.

Whatever the response here (except if it comes from Mark Andrews :-)
do not blindly accept it: test. Write a program which generates a
named.conf with one million zones and see what happens. This is sound
engineering practice, by the way and not BIND-specific: do not blindly
trust theoretical analysis, test.
