Split DNS with IPV6

Hi;

 

The following irule achieves split DNS in IPV4 world

 

when DNS_REQUEST { if { [IP::addr [IP::remote_addr] equals 10.0.0.0/8] \ or [IP::addr [IP::remote_addr] equals 192.168.0.0/16] \ or [IP::addr [IP::remote_addr] equals 172.16.0.0/12] } { pool poola }

 

else { pool poolb

 

}

 

How do achieve this in an IPV6 world and can I have one rule for both worlds.

 

Kindly Wasfi

    The irule is the same:

    when DNS_REQUEST {
log local0. [IP::remote_addr]
    if { [IP::addr [IP::remote_addr] equals 10.0.0.0/8] or [IP::addr [IP::remote_addr] equals 192.168.0.0/16] or [IP::addr [IP::remote_addr] equals 172.16.0.0/12] } {
        pool pool
    } elseif { [IP::addr [IP::remote_addr] equals 2a02:1111:2222:3333::0/64] } {
        log local0. [IP::remote_addr]
        pool pool
    }
    else {
        pool poolb
    }
}
