for IPv6) are the domain name and the DNS servers. If this server is alone on the local network (as defined by the broadcast propagation), the authoritative
directive must also be enabled (or uncommented). One also needs to create a subnet
section describing the local network and the configuration information to be provided. The following example fits a 192.168.0.0/24
local network with a router at 192.168.0.1
serving as the gateway. Available IP addresses are in the range 192.168.0.128
to 192.168.0.254
.

# # Sample configuration file for ISC dhcpd for Debian # # The ddns-updates-style parameter controls whether or not the server will # attempt to do a DNS update when a lease is confirmed.

case (see
قسمت 10.7.1, “DNS software”
), the allow-update
directive needs to be added to each of the zones that the DHCP server is to edit (the one for the internal.falcot.com
domain, and the reverse zone). This directive lists the IP addresses allowed to perform these updates; it should therefore contain the possible addresses of the DHCP server (both the local address and the public address, if appropriate).
allow-update { 127.0.0.1 192.168.0.1 212.94.201.10 !any };

را با یک سرور واگذارشده DNS مدیریت میکنند؛ یعنی فایل منطقه falcot.com
