I'd tell you that I want the DNS properly working on both sides :)

Also depends on who's more knowlegeable about DNS.

as long as an ISP wants to be slave for every domain on client's server,
every domain there means one zone definition at ISP.  as DNS manager I
wanted to have all domains properly working.  And since we had much more DNS
servers than most of our customers (one or two), I expected that

mostly depends on the current setup and real reason why the OP needed to
configure his master AND to call the ISP...
