[atlas] snmp

Hi, Is it possible to do snmp queries? I have a device on the internet. From some ip-adresses snmpwalk returns the whole list (about 6 entries), from some ip-addresses 1 + timeout and from most only a timeout. I would like to figure out what the pattern is. Can ripe atlas assist in that? I checked the user-interface but only found dns, ntp, etc. regards
