# servers previous to July 2010 had: restrict default noquery

restrict default kod nomodify notrap nopeer

# for local public lan segments
restrict a.b.c.d mask 255.255.255.0
restrict e.f.g.h mask 255.255.255.0

# for private lan segments
restrict s.t.u.v mask 255.255.255.0
restrict w.x.y.z mask 255.255.255.0

# for localhost
restrict 127.0.0.1
restrict -6 ::1 # only if ipv6 enabled

Servers have ntp traffic restricted by firewall rules and
in addition clients are behind NAT.

Client pcs (including laptops when used remote) are pointed to
my own servers. I think some have same restrict lines as
servers and others may have minimum:
restrict default noquery
restrict 127.0.0.1
restrict -6 ::1 # only if ipv6 enabled


Oh wow. Thanks very much for that detailed explanation. I'll try it out this afternoon.
