Yes but it depends what you're doing with them as to whether you need consent. If you're keeping a record of my IP address and what I do on your site to sell me stuff then yes you're tracking me and need my consent for that. If you've got my IP address in your logs because you keep security logs for reasonable timeframes then you don't need my consent - though you do need to handle them appropriately because it's my personal data.
