Hi,

The ASA can't act as DNS server or proxy-dns as far as I'm aware of.Even though it can serve as DHCP server or Relay,the features are limited compared to IOS and that's understandable because its primary focus is security.

Hi, Hope this will helpful to you. 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 for traceroute, and the ASA can resolve the name by communicating with a DNS server. Many SSL VPN and certificate commands also support names. Step 1 dns domain-lookup interface_name Example: hostname(config)# dns domain-lookup inside Enables the ASA to send DNS requests to a DNS server to perform a name lookup for supported commands. Step 2 dns server-group DefaultDNS Example: hostname(config)# dns server-group DefaultDNS Specifies the DNS server group that the ASA uses for from-the-box requests. Other DNS server groups can be configured for VPN tunnel groups. See the tunnel-group command in the Cisco ASA 5500 Series Command Reference for more information. Step 3 name-server ip_address [ip_address2] [...] [ip_address6] Example: hostname(config-dns-server-group)# name-server 10.1.1.5 192.168.1.67 209.165.201.6 Specifies one or more DNS servers. You can enter all 6 IP addresses in the same command, separated by spaces, or you can enter each command separately. The security appliance tries each DNS server in order until it receives a response.

Hi,

But this is not offering DNS services to clients as the OP asked.
