Re: [DNSOP] Definitions of foo-centric

[DNSOP] Definitions of foo-centric

Greetings again. People have asked us to define "delegation-centric", "child-centric", and "parent-centric" for draft-hoffman-dns-terminology. None of them are defined in RFCs, even though "delegation-centric" appears in RFCs 4956, 5155, and 7129. The terms are used in various places, so they se
