6:05 DNS can use either UDP or TCP. In both cases the well-known port used by the server
is port 53. UDP is used when the size of the response message is less than 512 bytes because most UDP packages have a 512-byte packet size limit. If the size of the response message is more than 512 bytes, a TCP connection is used.

great explanation sir, helped me complete the unit

You have very good teaching and explaining skills, but you should also add a web browser cache and PC host file in this packet flow.
IMPORTANT - DNS uses both TCP and UDP protocols. if there is packet loss while using UDP then DNS uses TCP protocol.

Hello Sir, DNS uses TCP for Zone transferring and UDP for name resolving

[iamdopped]

DNS uses both TCP for Zone transfers & UDP for Name queries.
So anything with data greater than 512 bytes we use TCP. Rest we use UDP.
Also UDP port 53 is used on server end.
