Subnet Design for Efficient Networks

The Internet continues to grow at a very rapid rate. Together with this growth there is an accompanying growth of the technologies on which it is based. These technologies make use of TCP/IP as their networking protocols. To use TCP/IP efficiently and reliably, networks that are based on these protocols must be designed, installed and maintained in as effective a way as possible. Underpinning all of these ideas is the principle of subnet design. This book takes the principles on which subnet design is based and develops them to fully explain the fundamental design concepts on which modern TCP/IP networks depend.This book is aimed at both the network professional and the enthusiastic network user. It explains how subnets work and the rationale behind their design and implementation. Through graded examples it guides the user from simple network issues and the associated calculation of the relevant subnet masks through to larger enterprise-level considerations for subnet designs.This a thorough understanding of how subnets workShows how to subnet the different classes of IP addressesProvides the design and calculations of variable-length subnet masksExplains how CIDR (supernetting) worksGives you an overview of how DHCP worksShows the integration of DHPC with subnetsExplains design consideration for network designsKeith Sutherland is a Microsoft Certified Systems Engineer specialising in TCP/IP, IIS and SQL server.
