Re: How 'bad' are spyware cookies??
said by Jason Levine  :However, if you delete adcompany.com's cookie (or refuse it in the first place), you appear to them to be a new person every time. Yes and no. I have detected my IP address in cookies served from various sites (not in a while though). I have also seen sites insert my IP address into the query strings and posted data from form submittal. So while deleting stored cookies will prevent most sites from tracking you it won't help if they are using your IP as a unique id unless your IP address changes frequently.

If your IP address changes frequently and you delete cookies before the IP changes over in all reality what can be done? |

| But who has a dynamic IP these days? My IP hasn't changed since the last time I shut the computer down when I went on vacation. That was Sept 2003. I bought this computer November 2003 and have had the same IP address all this time. I have Road Runner as my ISP. I have noted for years that if you want a new IP with Road Runner you must shut down the computers for at least 96 hours and sometimes it must be even longer. Three weeks will do it.

A cookie is not required to track you by your IP address (referring back to the earlier posts on IP addresses appearing in cookies.)
The other end has to know your IP address in order to send you back the information you've requested (the web page).
By the way, you can often force an IP address change by using a router the allows MAC address cloning. (Caution, if you happen to choose a MAC address that someone else on your ISP is using, you may find your IP address changing too frequently.)
