Well the first part looks like two script codes to me,or possibly a file name,probably generated by a BOT program,the second part i'm pretty sure is an I.P address.So while I can't tell you anything for sure,at my best guess that's a users private domain address (or several users,the cpe.net.cable.rogers.com part indicates that you only have part of the address,also that it's saying from one address to another)
