I'd be interested to know how many members of nznog saw the request to
join NewZ-Flash(a)domainz.net.nz, thought "bah, gratuitous use of mid-word
capitalisation, more marketing puff from Domainz", and chose not to join.
I know I did, and I'm grateful to Joe for filtering the content of
NewZ-Flash(a)domainz.net.nz and passing the interesting bits onto nznog.
Had the list been named domainz-annouce(a)domainz.net.nz, or
domainz-ops(a)domainz.net.nz, I'd almost certainly have joined the new
Now I'm not saying that's rational, you shouldn't judge a book by it's
colour, and all that, but that's the thought process I went through.
The rest of the email is a digression on the (in)accuracy of the numbers
offered by Patrick. Please ignore if you've got anything better to do.
<stuff deleted for brevity>
In the .nz Register, we've got just under 3,200
discrete "Technical contact"
addresses. Here's a list of the top 25 Technical Contact "user names" (I
mean the fields before the @..),
Let's see if my long forgotten stats 101 is up to this:
3200 tech contact email addresses
29966 total .nz domains, according to Mark Davies.
Only 776 domains are covered by the top 25 listed above, so 29190 domains
are shared out amongst another 3175 tech contact email addresses. By my
reckoning, that's over 9 domains per addressee, on average, but with a
maximum of 10, or they'd have made the list above.
This seems hugely implausible to me - if the 3178 addressees with 10 or
less domains are distributed evenly between 1 and 10 domains, then there
is only room for 17490 domains, which is way short of the count listed on
Mark's page. They'd have to be massively skewed towards 10 and away from
1 to allow for 29190 domains. Somebody with a better grasp of standard
deviations can comment on whether this is statistically plausible.
Stepping back from my inadequate statistical analysis, lets look at
specifics. nic(a)citylink.co.nz, nic(a)katipo.co.nz and nic(a)wellington.net.nz
all resolve to me, in various guises. A quick count in various bind config
files leads to me to believe that I am responsible for name servers
mastering for about 120 domains. Whenever I setup new DNS services for a
user, they get specific instructions to use one of the above email
addresses when they fill out the new domain form on www.domainz.net.nz
The vast majority of them do so, and therefore I would be suprised if
there are less that 100 occurrences of "nic" in the .nz registry.
As a check, I found 15 nic(a)katipo.co.nz's in the Domainz records for the
first 20 domains in the Katipo bind config (the rest were
simon(a)katipo.co.nz - oops :-). So the 10 listed for "nic" above, is,
bluntly, utterly wrong.
I'm not a big registrant, by any means, and I'm also not particularly anal
about enforcing that my users type the right info into the Tech contact
fields - if they want to put their own email addresses in, that's their
lookout. However, I believe that the big registrants generally do the
domainz rego on behalf of their users, and so it's fair to assume that
most of them are more rigorous than I. Therefore, it seems unlikely to me
that addresses such as dns(a)netlink.net.nz, soa(a)xtra.co.nz, and
operations(a)2day.net.nz have numbers as low as listed above. Perhaps the
relevant people could have fun with wget and grep and confirm this.
In reality, there is little clustering around a few
"generic" (soa, admin,
etc) names either -- "generics" comprising just over 18% of all names
That is absolutely *not* what the above data says. The above data says
(making the rash generalisation that the top 25 addresses are all
generics, and the only generics in the 3200 addresses) that generics
account for only 2.5% of the names chosen (this may be an invalid
assumption, but you'd expect generics to be towards the top of the list).
While generics may comprise only 18% of addressees, I'd love to know what
proportion of total domains are covered by generic addresses - I'd
hypothesise (and hope) that it would be much, much higher.
Obviously, this rant doesn't really add anything to the discussion about
email addresses, but I for one would be worried if Domainz were using such
patently wrong data as part of their decision making process.
