Lec-77: Domain Name Server(DNS) & its types in Hindi | All about DNS

[@souravsha]

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.

[@mehtajee1124]

Yes in made easy book also found that ..it uses both tcp and udp @port no. 53

[@ashwanijayee7359]

great explanation sir, helped me complete the unit

[@JagjeetSingh-ol4cx]

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.

[@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.

[@Patrick_J987]

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