It depends on what data is in the zones. If your data is static
e.g. no dynamic dns on the nameserver, then you might look for
a nameserver that works with files and needs no reloads.
e.g. tinydns (djbdns) works with files that are literally compiled
before feed to the nameserver and the nameserver "updates"
Bear in mind tinydns is not bind. It is designed completly
different and working differently. Always check with bind as a
reference if it does the right thing.
Same goes for the millions of other nameservers.
Group, please excuse me for mentioning another nameserver here.
I am running bind 9.4.0 myself and I am very satisfied with it.
Nevertheless I have to test and debug the others too :)
