Friends and Colleagues,

A new paper entitled “Study of the Prevalence of DNS Queries for CORP, HOME, and MAIL” has been released by ICANN’s Office of the CTO (OCTO).

This work studies the prevalence of Domain Name System (DNS) queries for domains ending in the top-level labels CORP, HOME, and MAIL in traffic to the root servers over an extended period of time. The frequency of queries and the number of unique source addresses are measured and compared to queries for other non-existent domains.

You can access the paper here >> https://www.icann.org/en/system/files/files/octo-007-en.pdf [PDF].

Thank you,

Fahd Batayneh
