In general, NSD works well as a replacement for BIND as an
authoritative-only server. However, it lacks one feature, which may, or
may not be important to you: you cannot add zones to, or remove them
from NSD without a restart. If you want to add a new zone, or remove
one, you have to stop NSD completely, rebuild the zone database, and
then start it again. This will cause downtime. Keep this in mind when
making your switch to NSD.
