Organisations do not need to defensively register other .llyw.cymru or .gov.wales domain names as their use is wholly controlled by WNAC.
Nid oes angen i sefydliadau gofrestru unrhyw enwau parth .llyw.cymru neu .gov.wales eraill at ddibenion amddiffynol gan fod gan Bwyllgor Enwi a Chymeradwyaethau Cymru reolaeth lwyr dros eu defnydd.
