"The advantage is that MyDNS simply reads the records
from the database, and it does not have to be restarted/reloaded
when DNS records change or zones are created/edited/deleted. A
secondary nameserver can be easily set up by installing a second
instance of MyDNS that accesses the same database or, to be more
redundant, uses the MySQL master / slave replication features to
replicate the data to the secondary nameserver.
"MyDNSConfig is an easy to use web-based interface to MyDNS-NG.
MyDNSConfig can create all types of DNS records that are available
in MyDNS and adds features like user management and access
privileges."
