I don't understand my IP address

I was surprised. My D-LINK router is supplying the addresses
192.168.0.100 and 192.168.0.101 for my two machines and has been for
some time.

This morning I was submitting something electronically to a company
and I noticed that it said my Internet address was 12.210.142.164,
which I assume is my real IP address? If it is, it bothers me that my
real address is determinable. Should I be?

Thanks

No, you should not be concerned. The router gets the real IP address
from your ISP and presents that to the outside world. Without having
that, you would not be able to "see" the Internet. The router then turns
around and gives private IP addresses to all the devices on the Local
Area Network. Private addresses are not browseable from the Internet.

What you are seeing is how things are supposed to work.

Your router has two different IP addresses. The first one is assigned by
your ISP. This address (12.210.142.164) is the one
known to the entire world. The second is the set of LAN numbers. These
addresses lie in the range of 192.168.x.x. Your
local machine is known to the router as either 192.168.0.100 or
192.168.0.101. As addresses in that range are not
routable, only your router knows your computers. Your router is responsible
for sending messages that it receives to the
correct machine.

In short, you have nothing to be concerned about. In fact, since this is
really just the "old hidden address trick", it is entirely normal.

Your internet service provider is supplying your modem an i/p address
and your router is supplying your computers their i/p addresses. They
are all real addresses. All is well.

Yes, it is your real IP address. How else do you expect the server on the
other end to send any data your way? Via some kind of voodoo or magical
fairy dust?
