Some end user applications are "Network Aware" , meaning they implement the application layer protocols and are able to communicate directly with the lower layers of the protocol stack. Email clients and web browsers are examples of these applications.

IP addresses Telnet traffic Upper-layer IP protocols
When an email client requests email over the internet, it primarily involves the following OSI layers: the Application layer (Layer 7) for protocols like SMTP and IMAP/POP3, the Transport layer (Layer 4) which uses TCP for reliable data transmission, the Internet layer (Layer 3) where IP addresses are used for routing, and the Data Link layer (Layer 2) which handles physical addressing and access to the network medium. These layers work together to ensure the email request is properly formatted, transmitted, and received.

IGRP and RIPv1
The network layer is the third level of the Open Systems Interconnection or the OSI model. The protocols that are implemented at this layer which carry user data include: Internet Protocol version 4 (IPv4), Internet Protocol version 6 (IPv6) and Novell Internetwork Packet Exchange (IPX).
