Description

Standard DNS does not allow CNAME records to coexist with other normal data, which is sometimes confusing for non-DNS experts who want to redirect one domain to the other, like example.com. -> example.net.

Various actors invented their own solution, be it ALIAS or ANAME RR types with non-standard backend software, and some others decided to just ignore the CNAME limitation in standards and put CNAME RR next to other data.

In this talk we will explore how real resolvers react to situation where CNAME RR and other data reside at the same node in DNS tree. Is the currently deployed code sufficient or do we need a new standard?
