IP networks

What you will learn:

You'll learn how routers build and maintain routing tables and explore the advantages of hierarchical addressing and how IP addresses are structured and allocated. The course also explains the role, operation, and administration of the domain name system that translates between web and IP addresses.

 

By the end of this course you will be able to:

• explain how a router selects an outgoing link for a packet by referring to its routing table.
• explain the concept and relevance of path cost giving examples of types of cost including hop count and available link bandwidth.
• describe the role and basic operation of a route discovery protocol with reference to sending advertisements and building routing tables.
• explain the advantages of hierarchical addressing
• explain the methods taken to make more efficient use of a limited pool of IPv4 addresses with reference to the use of subnetting, CIDR and private addresses.
• describe and compare the format of an IP version 4 (IPv4) address with that of an IPv6 address giving advantages of the latter.
• describe the role and administration of the domain name system.
• explain the operation of the domain name system with reference to ways of minimising its vulnerabilities to malicious use.
