New Report Presents Syntax and Operability Accuracy of WHOIS Data in gTLDs

13-Jun-2017 | Source : AG-IP News | Visits : 3233
LOS ANGELES - ICANN published the WHOIS Accuracy Reporting System June 2017 report. This latest report of the WHOIS Accuracy Reporting System (ARS) acts as a follow-on to the reports published in December 2016, June 2016, and December 2015.

According to ICANN, the report explores both the syntax and operability accuracy of WHOIS records in gTLDs as compared to the requirements of the 2009 and 2013 Registrar Accreditation Agreements (RAAs). It also examines the leading types of nonconformances, trends and comparisons of WHOIS accuracy across ICANN regions, RAA versions and gTLD types.

ICANN developed accuracy tests to answer questions about the syntax (format and content) and operability (e.g., does an email sent to the email address provided in the WHOIS record go through?) of a sample of WHOIS records. Then, using statistical methods, syntax and operability accuracy estimates with a 95 percent confidence interval were provided for the population of domains in gTLDs as a whole, as well as for several subgroups of interest.

Key Findings

The analysis found that:
Nearly all WHOIS records contain information that can be used to establish immediate contact: In 98.6 percent of records, at least one email or phone number meets all operability requirements of the 2009 RAA.
Approximately 94 percent of email addresses, 69 percent of telephone numbers and 97 percent of postal addresses were operable (see Table 1 below for more information).
Table 1: Overall gTLD Operability Accuracy by Contact Mode (95 percent confidence interval)
Email Telephone Postal Address All 3 Accurate
All 3 Contacts (Registrant, Technical, Administrative) Accurate 94.5% ± 0.5% 68.9% ± 0.8% 97.2% ± 0.3% 65.4% ± 0.9%
In terms of syntax accuracy, approximately 99 percent of email addresses, 90 percent of telephone numbers and 87 percent of postal addresses were found to meet all the requirements of the 2009 RAA (see Table 2 below for more information).

Email Telephone Postal Address All 3 Accurate
All 3 Contacts (Registrant, Technical, Administrative) Accurate 99.5% ± 0.1% 89.5% ± 0.6% 87.4% ± 0.8% 79.3% ± 0.8%
The report also shows a breakdown of accuracy rates by ICANN region (see Figure 1 below for more information).
