Written iRule with help of if & elseif condition. Please check & let us know if any confusion.

   when DNS_REQUEST { 
    if { [IP::addr [IP::remote_addr] equals 192.168.163.0 mask 255.255.255.0]} {
        if {[LB::status vs 192.168.163.39 ] eq "up" } {
                host 192.168.163.39 } 
        else { 
            host 192.168.204.45 }
    elseif { [IP::addr [IP::remote_addr] equals 192.168.165.0 mask 255.255.255.0]} {
        if {[LB::status vs 192.168.163.39] eq "up" } { 
            host 192.168.163.39 }
        else { 
            host 192.168.204.45 }
    elseif { [IP::addr [IP::remote_addr] equals 192.168.204.0 mask 255.255.255.0]} { 
                    if { [LB::status vs 192.168.204.45] eq "up" } { 
            host 192.168.204.45 } 
        else { 
            host 192.168.163.39 }
                }
        }
        }

Can you please try now...

    when DNS_REQUEST {
        switch [IP::remote_addr] {
          "192.168.163.0/24 “ {
if { [LB::status vs 192.168.163.39] eq "up" } {   
   host 192.168.163.39 } 
   else { host 192.168.204.45 }
}
  "192.168.165.0/24] " {
if { [LB::status vs 192.168.163.39] eq "up" } {
    host 192.168.163.39 } 
    else { host 192.168.163.39 }
}
 "192.168.204.0/24] " {
if { [LB::status vs 192.168.204.45] eq "up" } {
   host 192.168.204.45 } 
   else { host 192.168.163.39 }
    }
}
