RE: Suggestions for the Internet Corporation for Assigned Names a nd Numbers


I agree with your premise, but I don't believe it conflicts with my
assertion.  I am not advocating unmanaged growth of TLD's for growth sake.
I am suggesting the avoidance of artificial limits based on technology
determinations made long ago.

I still see a number of arguments for keeping zones small:

- The larger the zones, the higher risk of getting operational problems. 
This because if nothing else the number of changes in a large zone is 
larger than the number of changes in a small zone. The fact that one change 
a zone increase the risk of differences between the replicated DNS servers 
for the zone.

- Even if we have a lot of TLDs, we will still have problems with 
uniqueness of names, and the true fact that one TLD creates a monopoly -- 
regardless if we have 10, hundred or millions of TLDs. Each one will be a 

- DNS is a hierarichal system. It is designed to be hierarichal. A flat 
namespace in not what will work, because of uniqueness and other issues.

Increasing the number of TLDs don't solve the problem people normally see 
with the few gTLDs we have.

   In theory there is no difference between theory and practice,
   but in practice, there is.
