Spam from weird IP 118.189.136.119

Getting SPAM from 118.189.136.119 relayed by rr.com ? this network is not allocated, nor announced. I have been looking everywhere to find if it has been announced (historical bgp update databases, like RIS RIPE / CIDR REPORT / etc..)... I didnt found anything.... this probably mean rr.com is routing that network internaly. "Received: from [118.189.136.119] by smtp-server1.cfl.rr.com with NNFMP;" If there is any rr.com guy around. Could you please check this? Thanks, Pascal
