+DHCP-provided NTP servers
+-------------------------
+
+When ``CONFIG_NETUTILS_DHCPC`` is enabled, the DHCP client can pass NTP
+server IPv4 addresses learned from DHCP option 42 to ``ntpc``.
+
+This allows ``ntpc`` to run without a fixed server hostname in the
+configuration and to follow NTP server updates delivered by DHCP.
+
+One way to test DHCP-delivered NTP servers is with ``dnsmasq``:
+
+::
+
+   dnsmasq --no-daemon --log-dhcp --log-queries \
+     --interface=tap0 --bind-interfaces \
+     --dhcp-authoritative \
+     --dhcp-range=192.168.50.20,192.168.50.50,255.255.255.0 \
+     --dhcp-option=option:router,192.168.50.1 \
+     --dhcp-option=option:dns-server,1.1.1.1 \
+     --dhcp-option=option:ntp-server,162.159.200.123
