Managing Domain Name System

Managing Domain Name System (DNS) includes verifying that the DNS function is working, monitoring performance, and maintaining DNS data and files.

• Verifying the Domain Name System function is working
  Name Server Lookup (NSLookup) is a tool that is used to query the Domain Name System (DNS) server for an IP address. This verifies that the DNS server is working.

• Managing security keys
  Security keys allow you to limit access to your Domain Name System (DNS) data.

• Managing Domain Name System keys
  The Domain Name System (DNS) keys are keys defined for BIND and used by the DNS server as part of the verification of an incoming update.

• Managing dynamic update keys
  Dynamic update keys are used for securing dynamic updates by the Dynamic Host Configuration Protocol (DHCP) server.

• Accessing Domain Name System server statistics
  Database dump and statistics tools can help you review and manage server performance.

• Maintaining Domain Name System configuration files
  You can use i5/OS^® DNS to create and manage DNS server instances on your System i™ model. The configuration files for DNS are managed by iSeries™ Navigator. You must not manually edit the files. Always use iSeries Navigator to create, change, or delete DNS configuration files.

• Advanced Domain Name System features
  DNS in iSeries Navigator provides an interface with advanced features for configuring and managing your DNS server.
