What OSI layer is DNS?

At a high level, the DNS protocol operates (using OSI model terminology) at the application level, also known as Layer 7. This layer is shared by HTTP, POP3, SMTP, and a host of other protocols used to communicate across an IP network.


DNS has always been designed to use both UDP and TCP port 53 from the start 1 , with UDP being the default, and fall back to using TCP when it is unable to communicate on UDP, typically when the packet size is too large to push through in a single UDP packet.

Is DNS query TCP or UDP?

Why does DHCP use UDP?

Originally Answered: Why does dhcp uses udp? The very first message DHCP sends is DISCOVER which is a broadcast message as the client has no idea what DHCP server’s IP address is. TCP doesn’t support broadcasts. So we use UDP.

Why does DHCP have 2 ports?

The reason TWO reserved ports are used, is to avoid ‘waking up’ and scheduling the BOOTP server daemons, when a bootreply must be broadcast to a client. Since the server and other hosts won’t be listening on the ‘BOOTP client’ port, any such incoming broadcasts will be filtered out at the kernel level.

What are the 4 steps of DHCP?

DHCP operations fall into four phases: server discovery, IP lease offer, IP lease request, and IP lease acknowledgement. These stages are often abbreviated as DORA for discovery, offer, request, and acknowledgement.
