DNS< TCP/IP etc

Having covered things like DNS, TCP/IP, TCP/IP uilites in Net+ is it ok to skip these chapters in the 210 book or should I still go through it, and look at chapters I need like Active directory etc, or should I still focus on these areas?

Future planned exams are as follows: CCNA, Windows 2003 Server 70-290
