What does it mean for the IDN ccTLD manager that domains under synchronized IDN ccTLDs must resolve to the same address or value?
As above, the goal is to ensure an appropriate user experience, not to mandate identical answers to DNS queries at the protocol level. The requirement is that the registry operator has mechanisms in place that ensure that queries for names under “domainname.syncTLDa” and queries for names under “domainname.syncTLDb” result in a similar end-user experience. In addition, mechanism must be in place to ensure as far as possible that the synchronization in continued beyond the second level under the IDN ccTLDs. Review and correction procedures must be in place to remedy any situations where this is not the case.
