DNS irule for resolving FQDN with a IP - LTM

Hi.

If you want to use DNS in irule unsing LTM you must have necessary license (DNS Services license)

try this:

when DNS_REQUEST {

set host [DNS::question name]

  switch -glob $host {
    "hostname1.domain.com" { 
        DNS::answer insert "[DNS::question name]. 300 [DNS::question class] [DNS::question type] 1.1.1.1"
        DNS::return
    }
    "hostname2.domain.com" { 
        DNS::answer insert "[DNS::question name]. 300 [DNS::question class] [DNS::question type] 1.1.1.2"
        DNS::return
    }
    default {
        do nothing
    }
  }
}
