Important Considerations
■
The Domain Name System (DNS) client provides DNS lookup
functionality to the CoreBuilder IP ping and traceRoute features. You
can specify a host name rather than an IP address when you perform
various operations (for example, when you use
ping
or
traceRoute
to
contact an IP station).
■
With the DNS commands, you specify one or more name servers that
are associated with a domain name. Each name server maintains a list
of IP addresses and their associated host names. When you use
ping
or
traceRoute
with a host name, the DNS client attempts to locate
the name on the name servers that you specify. When the DNS client
locates the name, it resolves it to the associated IP address.
■
See UNIX Network File System (NFS) documentation for information
about how to create and maintain lists of domain names and IP
addresses on the name servers.
