Certification Summary


DNS provides a database of domain names and IP addresses that help Web browsers and more find sites on the Internet. The default DNS server for RHEL uses the Berkeley Internet Name Domain (BIND). It's a distributed database for which each administrator is responsible for his or her own zone of authority.

DNS can be controlled with various rndc commands. The diagnostic tool for DNS is now dig. You can also use the more traditional nslookup command, but it has been deprecated in RHEL 5.
