Hi grisihb,

Can you try this?

when DNS_REQUEST {
	if { [IP::addr [IP::client_addr] equals 10.10.10.0/24] } {
		host 10.11.12.13
	} else {
		cname www.redirect.domain.com
	}
}

Here is my question.. in code, client_addr is requester (source) ip address or its LDNS IP ?

  I think, client_addr is the LDNS IP.
