You may not have seen anything above 11 if you're in the US or Canada. Some people get equipment which is designated for other countries or hack the firmware to add additional channels. So you may occationally see channels 12-14 in the US or Canada. (BTW, running such equipment in a country is where the equipment isn't compliant is illegal.)
DHCP is a TCP/IP and networking function, it has nothing to do with NS.
