Configuring the DNS Server
Some ASA features require use of a DNS server to access external servers by domain name; for example,
the Botnet Traffic Filter feature requires a DNS server to access the dynamic database server and to
resolve entries in the static database. Other features, such as the ping or traceroute command, let you
enter a name that you want to ping or traceroute, and the ASA can resolve the name by communicating
with a DNS server. Many SSL VPN and certificate commands also support names.
Note
The ASA has limited support for using the DNS server, depending on the feature. For example, most
commands require you to enter an IP address and can only use a name when you manually configure the
name command to associate a name with an IP address and enable use of the names using the names
command.
For information about dynamic DNS, see the
Prerequisites
Make sure that you configure the appropriate routing for any interface on which you enable DNS domain
lookup so you can reach the DNS server. See the
more information about routing.
