Embedded DNS Resolution

The embedded DNS supports the non-default name resolution. The DNS client interacts with a DNS server to perform the name resolution. The new SAF dns-lookup, receives the DNS server's IP address as a server argument. This IP address should be added as a DNS directive in the obj.conf file.

In the following example, IP of the DNS server is specified in the server parameter.

<object>
....
DNS fn="dns-lookup" server="170.168.10.3"
...
</object>

In the following example, you can add multiple DNS server IPs to dns-lookup-init, and it will be used in round robin model. In this scenario, do not add DNS server IP to dns-lookup. If DNS server parameters are added to both dns-lookup and dns-lookup-init, the dns-lookup argument will take the precedence.

...
<Object>
...
DNS fn="dns-lookup"
....
Init fn="dns-lookup-init" servers="170.168.10.3, 170.158.10.4"
</Object>
