A CNAME node contains only CNAME, + RRSIG(CNAME), NSEC, RRSIG(NSEC), NSEC3, or RRSIG(NSEC3) rdatasets. + An "other data" node contains any rdataset other than a CNAME or + RRSIG(CNAME) rdataset. The enforcement is "last update wins". For + example, if you have a node which contains a CNAME rdataset, and + then add an MX rdataset to it, then the CNAME rdataset will be deleted. + Likewise if you have a node containing an MX rdataset and add a + CNAME rdataset, the MX rdataset will be deleted. + 2.1.0 ---------------------- -- 2.47.3
