- Returns the last module to modify the DNS message. Return values:
This message has just been received by the BigIP from a client’s query, and nothing has been processed.
This message has just been received by the BigIP from a server’s response to a DNS query, such as On-Box or Off-Box BIND, or another BigIP entirely.
This message is a response from the DNS Cache.
This message is a response from the Response Policy Zone in your BigIP. It was blocked and either NXDOMAIN or a Walled Garden was returned as a response.
GTM built this response in it’s entirety
GTM did not build the response completely, but modified the response on its way out, such as adding or removing an answer populated by another GTM component. This could occur when the already populated answer includes a pool member that is no longer available, or lacks one that is now available, for example.
This means that the DNS Response received was answered by the BigIP’s DNS Express module.
This means that you queried for a DNSSEC type and got a DNSSEC-typed answer. An example command is “dig @126.96.36.199 example.com +dnssec DNSKEY”
This means that “Unhandled Query Action” was the last thing to handle this packet. So, for example, if you have this set to “Reject”, then by the time it gets to the “Unhandled Query Action”, it will respond with “Status Refused” and this originates from “LAST_ACTION”
An iRule modified the DNS response.
