Does an IP Address reveal our identity?

[fppf]

It not so much the IP address, its the MAC address of the modem. The MAC address of the modem never changes, the DHCP server uses this to assign IP addresses. Most times the DHCP server will give you the same IP, unless your provider is really screwing with you and rotates them.

In short, changing the IP address with the DCHP server does not make you any less tracable. Now, if you reflash the MAC on your cable modem that would work. However the ISP uses the MAC on your modem to control your account, IE if you don't pay they block that MAC.

FPPF.... who blocks the MAC? The folks who want the money or my ISP? I havent heard of this before...

If you don't pay your ISP for your internet service the way they shut off your cable modem is by blocking any requests and reverting them to the ISP's you need to sign up page. They do this with the MAC address of the modem. That is why when you sign up they record the MAC address on the modem. I'm sure you pay your cable bill or who ever your ISP is

This has nothing to do your your little situation from Tonga, there not your ISP.

Packets contain the MAC address of the last router that handled the packets, not the sender. It's not possible to obtain the sender's MAC address from across the internet.

Absolutely correct.

(Unless you can remotely access your personal router management screens, which I do all the time), and identify MAC / IP's of your internal network). A good case for changing your default router username/password...

Bottom line, Diveress... don't sweat it...

I don't believe my post says that a someone can get your MAC address across the internet.

Just pointing out that your ISP does not us IP addresses to identify someone.
