Since this is NANOG, I decided that some technical/numeric accuracy was good:

Nowadays, taking annual fees into account, the number of parties owning

thousands of domain names is dropping quickly. Okay, so let's say it is a

ten-to-one ratio (which it's not, I believe it is more like 1.5 to one) ...

1.2 million doesn't apply to COM, it appears to be the estimate of the

combined size of COM, NET, and ORG. Last week when I measured it, COM

had 942952 delegations under it (that is, second level domains) but they

were served by only 54292 discrete nameservers. (Note that DNS's anti-

aliasing is weak, and given BIND 8.1's virtual hosting capabilities it

is likely that those 54292 "nameservers" are running on some smaller

number of real live actual physical hosts.)

However, given the raw numbers the ratio is such that the mathematically

average nameserver has 17.36 COM zones delegated to it (which includes

master ("primary") and slave ("secondaary").) Eventually I'll start doing

histograms so I can tell y'all what the mean is and how lopsided the figures

really are. Suffice to say that 1.5 is the wrong number, and that 10 is

actually closer to the truth.
