Amazon, Google or Demand Media are going to have to block over 200,000 strings in .wow, which all three have applied for, due to the risk of name collisions.
That’s tens of thousands of names greater than any other applied-for gTLD string.
Here’s the top 20 gTLDs, ranked by the number of collisions:
The average new gTLD string has 7,346 potential collisions, according to our preliminary analysis of the lists ICANN published for 1,318 strings this morning.
As blogged earlier, 9.8 million unique domain names are to be blocked in total.
Seventeen gTLDs seem to have been provided with empty lists, so will not have to block any domains in order to proceed to delegation with ICANN.
