Summary

The process that computers use to translate a meaningful domain name to an IP address allows users to better use and understand services available on a network. DNS becomes even more important with the advent of IPv6 and 128-bit hexadecimal addresses. The operation of DNS and the tools mentioned today allow you as an administrator to better troubleshoot DNS-related issues. You can review TCP/IP and DNS on pages 39–68 of CCNA Flash Cards and Exam Practice Pack (CCENT Exam 640-822 and CCNA Exams 640-816 and 640-802), Third Edition.
