Answer / rajeev
DNS uses TCP for Zone Transfer over Port: 53
DNS uses UDP for DNS Queries over Port: 53
A client computer will always send a DNS Query using UDP
Protocol over Port 53. If a client computer does not get
response from a DNS Server, it must re-transmit the DNS
Query using the TCP after 3-5 seconds of interval.

Answer / srinivas podapati
DNS uses TCP for Zone transfer and UDP for name queries
either regular (primary) or reverse. UDP can be used to
exchange small information whereas TCP must be used to
exchange information larger than 512 bytes. If a client
doesn't get response from DNS it must re-transmit the data
using TCP after 3-5 seconds of interval.
