ENVS 1000 Lecture 36 Notes – Addressing
Introduction
• The ability to tie multiple network devices into a network require addressing standards
that are implemented for every device attached to the network.
• When the network is interconnected with other networks, the requirements for
addressing are even more stringent, and the addressing standards must apply globally.
• TCP/IP is typical of network models in this respect.
• TCP/IP requires addresses to specify the applications responsible for message
communication, the addresses of the sender and receiver nodes plus all intermediate
nodes involved in a communication.
• Finally, a physical address that selects a particular node within a network.
• A user creates a message at the application layer.
• Like any messaging system, the user must also specify the address of a receiver for the
message.
• The message could be a print server request, a Web request, an e-mail message or any
other application-based message.
• The user will normally specify this address as a user-friendly address: a URL such as
www.youtube.com, or an e-mail address such as [email protected], or perhaps
even the name of a printer on the local network.
• User-friendly addresses allow a user to work with addresses that are familiar and
understandable.
• To be effective, user-friendly addresses must be global in scope if they are to exist
outside the confines of an isolated network.
• There must also be no possibility of duplicates.
• The use of a standard global domain name system with required name registration
provides these assurances and provides a hierarchical system for name creation and
registration and tools for locating and identifying specific names.
• TCP/IP requires addresses to be specified numerically in the form of IP addresses.
