DNS is the Domain Name System, which maintains a database that can help your computer translate
domain names such as www.Redhat.com to IP addresses such as 216.148.218.197. As no individual DNS server is large enough to keep a database for the entire Internet, they can refer requests to other DNS servers.
DNS is based on the named daemon, which is built on the BIND (Berkeley Internet Name Domain) package developed through the Internet Software Consortium Users wants to access by name so DNS will interpret the name into ip address. You need to specify the Address if DNS server in each and every client machine. In Redhat Enterprise Linux, you need to specify the DNS server into /etc/resolv.conf file.
After Specifying the DNS server address, you can verify using host, dig and nslookup commands.

RHCE是Red Hat Certified Engineer的簡稱，始於1999年3月。截至2001年1月17日，Red Hat的統計資料表明，RHCE資格認證的通過率為62.5%。RHCE是市場上第壹個面向Linux的認證考試，它不是壹個普通的認證測試，和其他操作系統認證考試相比，RHCE考試需要花費壹整天的時間，而且在測試中更加註重考察考生的實踐經驗。Red Hat官方將RHCE考試分為兩個級別：專家級和標準級。專家級要求考生有多年的UNIX/Linux系統管理和網絡配置、管理經驗，其中RH302是和RH300捆綁的實踐操作考試，如果考生認為自己經驗豐富，不用學習RH300課程，可以直接參加RH302的實踐操作考試。
