Table of top DNSSEC hosted domain counts by MX host zone (parent domain). The status flag is:

– for unsigned provider zones.
+ for signed provider zones, but no MX hosts have TLSA records.
d for signed provider zones, domains served by MX hosts without DANE TLSA records
D for signed provider zones, domains served by MX hosts with DANE TLSA records.

Where the zone is signed, but DANE is not yet broadly deployed, publishing TLSA records would be a good way to get more value for the price of having DNSSEC.

Note that in a few cases the provider is only a backup MX for the hosted domains, and the primary MX hosts may not be DANE-enabled.
