WHOIS Right? An Analysis of WHOIS and RDAP Consistency. Un paper sulla coerenza tra WHOIS e RDAP, ora che conviveranno per un po'.
In this paper, we examine the core assumption that WHOIS and RDAP offer the same data and that users can query them interchangeably. By collecting, processing, and comparing 164 million WHOIS and RDAP records for a sample of 55 million domain names, we reveal that while the data obtained through WHOIS and RDAP is generally consistent, 7.6% of the observed domains still present inconsistent data on important fields like IANA ID, creation date, or nameservers.
