thanks for posting , helps so i can point people to this post without having to explain all that everytime
a question though i have always wondered , as you mentioned seo is not a justification for arin ip requests, yet many hosts offer multiple ip's for just that, i am not an expert in this field, but as i have read ip's can be revoked by arin if they arent being used for the purpose arin outlines. Do seo hosts run the risk of ip's being revoked ? have you ever had ip's revoked ? can you give us any more details on this.
