I'm perfectly aware, thankyouverymuch.
And what happens to ".re" relative to ".com" has nothing to do
with the story.
.edu versus .com then, or .au versus .com, or anything you want. There are
millions of organizations that don't issue queries for those zones either.
Perhaps somebody will be kind enough to post some actual per-TLD
statistics for those zones.
If something like .pr0n (being sensitive to mail filters) starts taking
out a massive number of .com sites, there will be fewer queries for .com.
No question about it. Saying that there will be no more queries for .com
is fairly ludicrous, but it can be sustainably argued that some networks
will timeout their internal caches for longer periods, resulting in a
slight lowering of .com lookups. Meanwhile, there will be lots of networks
that NEVER lookup any domain in the .pr0n TLD. Furthermore, domains which
had been operating under .kr, .ru, .uk and so forth will also move,
resulting in those tertiary zones getting fewer root queries. So even
though there may be an equal number of domains under the .com and .pr0n
titan TLDs, the overall load will likely have only gone up by a few
percentage points. This is especially true if the overall number of
resolver-side queries is consistent.
