But its fairly obvious that you're in unsure waters for yourself.
Yes, you can know the IP of someone when they visit your web page. That's easy since the web page wouldn't be able to respond to you if it didn't know your IP.
But your IP is not an ID badge. It can and does change. Maybe next week, like I said, was a little faster that actual but possibly tomorrow, you'll get assigned a new IP. Hell, maybe today.
The reason your IP didn't change last night is because of a DHCP lease. You keep the same IP for the duration of the lease.
And who is "they" that can easily track you? Again, you're unsure of what you're talking about here. I didn't say you can't be tracked at all. I said that to do so would require the ISP (or malware on your PC) to update the obamacare database with your new IP every time it changes. It's similar to how a Dynamic DNS updater works. Let's say you sign up for dyndns.com's service. Every time your IP changes, it updates your DNS records with your new IP so that internet traffic can find you by URL. You can't host a web server at your home without one of these services because your DNS record would become incorrect frequently. You'd have to manually check your IP and update your records, which takes 2-72 hours to propagate through the interweb's publicly available DNS servers.
The notion that when you visit the obamacare websites allows them to track you by your IP is dumb since by the time they care to look, it could have easily changed.
The reason sites can track you is because of "tracking cookies", not because your IP is static. Want to stop it? Set your browser to clear cookies on exiting. Or just clear them yourself. Or don't allow them to be installed in the first place.
And just so you know... some people (my clients, including military contractors, international treaty orgs and international manufacturers) consider me to be an expert. That's why I get to eat every day. The truth is, to experts, I'm pretty good. To amateurs, I'm a total wizard.
I'm not trying to sell you a load of shit like the naturalnews site is.
