Hi Mark, what is the specific RR query you are looking for? currently we support a bunch of them UDP or TCP. Here is a list. in class IN A, AAAA, ANY, CNAME, DS, DNSKEY, MX, NS, NSEC, NSEC3, PTR, RRSIG, SOA, SRV, NAPTR. class CHAOS hostname.bind, id.server, version.bind, version.server regards, -antony On Wed, Feb 19, 2014 at 03:54:29PM +0000, Mark Delany wrote: > Outside of Atlas I've been doing a few tests to see how well CPE > supports newer RR types.
