DNS is an application layer protocol. The application layer of the OSI model is the layer closest to the user and provides network services to the applications of the user. Examples of protocols that operate at the application layer are: DNS, FTP, TFTP, SNMP, TELNET, RLOGIN, SMTP, MIME, NFS, FINGER, BOOTP and SMB.

because ICMP stands for internet control Message Protocol. It is a network protocol so ICMP operates network Layer of the osi model.

In the 7 layers of the OSI model, DNS works in the 7th layer i.e application layer which is a human-computer interaction layer, where we can access applications and network services.

How telnet function in OSI model?
Telnet is an application layer protocol (Layer 7). Its functionality is similar to any of the layer 7 protocols, including DHCP, DNS, FTP, etc.
Role of OSI application layer?
Think in terms of HTTP (HyperText transfer protocol), FTP (file transfer protocol), DNS (domain name services) and DHCP (dynamic host configuration protocol). The application layer is the highest level, layer 7 of the OSI an ISO (International Standards Organization) (Open Systems Interconnect) model. ISO falls under the ANSI (American National standards Organization). This is an old standard and I believe the layers have been redefined once or twice over the years. Generally you can think of the application layer as what is on the screen in front of you. If you download a web page, open an email or get an IM (instant message) from someone you are looking at the application layer. Remember that the presentation layer 6 just below application may have done some data formatting, decrypting or conversion of some kind before the data is actually visible at the application layer.

What two protocols are most likely being used as the TCP IP model application layer protocol and the internetwork layer protocol?
The TCP/IP suite includes the following protocols Data Link Layer: ARP/RARP Address Resolution Protocol/Reverse Address DCAP Data Link Switching Client Access Protocol Network Layer: DHCP Dynamic Host Configuration Protocol DVMRP Distance Vector Multicast Routing Protocol ICMP/ICMPv6 Internet Control Message Protocol IGMP Internet Group Management Protocol IP Internet Protocol version 4 IPv6 Internet Protocol version 6 MARS Multicast Address Resolution Server PIM Protocol Independent Multicast-Sparse Mode (PIM-SM) RIP2 Routing Information Protocol RIPng for IPv6 Routing Information Protocol for IPv6 RSVP Resource ReSerVation setup Protocol VRRP Virtual Router Redundancy Protocol Transport Layer: ISTP Mobile IP Mobile IP Protocol RUDP Reliable UDP TALI Transport Adapter Layer Interface TCP Transmission Control Protocol UDP User Datagram Protocol Van Jacobson compressed TCP XOT X.25 over TCP Session Layer: BGMP Border Gateway Multicast Protocol Diameter DIS Distributed Interactive Simulation DNS Domain Name Service ISAKMP/IKE Internet Security Association and Key Management Protocol and Internet Key Exchange Protocol iSCSI Small Computer Systems Interface LDAP Lightweight Directory Access Protocol MZAP Multicast-Scope Zone Announcement Protocol NetBIOS/IP NetBIOS/IP for TCP/IP Environment Application Layer: COPS Common Open Policy Service FANP Flow Attribute Notification Protocol Finger User Information Protocol FTP File Transfer Protocol HTTP Hypertext Transfer Protocol IMAP4 Internet Message Access Protocol rev 4 IMPPpre/IMPPmes Instant Messaging and Presence Protocols IPDC IP Device Control IRC
What three protocols operate at the application layer of the OSI model?
There are many more than three protocols which can operate at the application layer. Some of these are; Telnet FTP TFTP SMTP IMAP POP DNS RARP BOOTP SNMP CMOT
What layer of the OSI model is most significant?
The OSI model represents a simple framework for discussing network protocols and therefor has no most significant portion. Lower level protocols like TCP/IP span several layers while Frame Relay and MPLS fit neatly in to a single layer. Higher level protocols like DNS and DHCP can be transport independent and don't necessarily require any of the lower layers to function.
Which protocol relies on DNS for name resolution?
DNS is Domain name system for short . Domain name system maps a name to an address. Protocol that relies upon DNS is TCP/IP .tcpip protocol
Which protocol use resole ip address?
DNS protocol.
Who invented the DNS protocol?
suseth
What is dns protocol?
DNS protocol was created to convert human domain names into IP address (intenet operates on IP addreses).
What protocol uses both TCP and UDP?
DNS does.
What is the primary protocol used for Name Resolution?
dns
What is DNS stand for?
TCP/ IP protocol suite uses a DNS client. DNS stands for Domain name system .A DNS server maps a name to an address.
