With the exception of DNS, they have to work this way. DNS can use
either TCP, UDP, or both. Most systems default to UDP first for
historical reasons.

My question is: what is the reason behind it? why not use TCP servers
for DNS or for NTP or for  DHCP?

DNS: Sure, you can. Lots of people do.
NTP: Wouldn't work. TCP's transmit pacing would make NTP totally
DHCP: Wouldn't work. There is no broadcast TCP.
