Incase of ISPs which assign dynamic IPs it may not work as expected. For ex., User A -> Gets IP - IP1 -> Votes -> Disconnects User B -> Gets IP - IP1(dynamic IP) -> Tries to vote - failure, pissed off - Never voted in first place Let me know if my logic is right. Currently I am resorting to assigning a cookie first time user visits a site with cookie contents being IP and the first time user visits the site. Thanks -- Prasad http://roorky.com Interactive Programming Books Hi,

User B -> Gets IP – IP1(dynamic IP) -> Tries to vote – failure, pissed off – Never voted in first place

Let me know if my logic is right. Currently I am resorting to assigning a cookie first time user visits a site with cookie contents being IP and the first time user visits the site.

I set it up quite simular to this, however, instead of having any logic in the controller to check I simply added a line in the model: validates_uniqueness_of :client_ip I actually just created a small rails based pull.
