Resending, since this seems to have gone AWOL
While this study probably has some merit, I'm having difficulty understanding
exactly where that merit actually lies.
There are over 100 million gTLD domain names currently registered.
To draw any "meaningful" conclusions about anything related to the current
corpus of domain names would require a sample set significantly larger than
that chosen.
While it may be possible for a statistician to rationalise their choices I
would be wary of making any definitive statements about WHOIS based on this
sample.
With respect to the study's methodology ...
"We explored with ICANN the possibility of using IP address and Maxmind.com to
assign countries to all domains prior to sample selection in order to avoid
this additional stage of sampling, however once we checked the country
assignments using those sources against actual country as recorded in a sample
of WHOIS records we found too many inaccuracies."
IP addresses are NOT assigned by country. They are assigned firstly by region
ie. RIPE, ARIN etc., and then to AS numbers, which have no direct correlation
with countries. We, for example, are members of RIPE. That does not, however,
mean that all our IP assignments are going to be mapped "easily" to Ireland. If
we assign an allocation to a client from Portugal, then the IP address'
assignment would reflect that clearly in WHOIS.
The only case where Maxmind, or a similar service, would "fail" is if the IP
block being queried were a very recent one and considering that Maxmind update
their database every few days even that assertion is probably inaccurate.
The methodology for verifying physical addresses may work fine in countries
with an easily "mappable" postal address system, but my own home address would
probably fail their checks, as would a lot of Irish residents.
Using phone numbers to validate contacts is fine, however expecting to be able
to do a lookup is not. It's 2010. Many people rely primarily on their mobile
phone for day to day use, and most of our staff, for example, wouldn't even
have fixed lines in their homes. And of course there are no public directories
of mobile phone numbers.
In any case until such time as gTLDs adopt a saner approach to WHOIS that
respects individuals' right to privacy this "problem" won't go away.
A criminal is never going to provide valid WHOIS data and in many of the cases
I've seen will quite happily produce perfectly valid WHOIS data - just not
their own
