Hi Wilfried, Quick mental counting suggests that there are 3 different options: 1) if resolve-on-probe is not set, the target is resolved by the Atlas backend and the probe only gets the IP address. The (glibc) stub resolver on CentOS does not do any case mangling. 2) if resolve-on-probe is set then the probe resolves the target using the stub resolver in libevent. This stub resolver mangles the case. 3) for DNS measurements, the domain name parameter is used as is. However the target of the measurement is subject to case 1 or 2. Philip
