IP Addresses.

Hello Folks, Could someone please explain the difference between an 'internal' and an 'external' IP address? Sometimes I use PCPITSTOP .COM tune up. The information I get back includes both addresses. I know that the 'internal' address is correct. I don't know about the 'external' address as I don't know how to find it. Any information would be appreciated.
Regards, William.

Normally....
External is the IP that NTL servers and anyone outside of your LAN will see. Internal IPs are for your internal network only (computers your side of the modem).

Hello Paul, Many thanks for your reply. Is it normal for the like of PCPITSTOP to be able to read my 'internal' address or does it matter? Regards, William.

Do you run a firewall? If not you may want to.

Yes Paul. I use Norton Internet Security that was pre -installed on the computer and renewed about 6 months ago. William.

Might need to tweak it a bit then. Try running the firewall test here:

Hello Paul, Ran the firewall test. Got a 'pass' for each test. System described as 'Tru Stealth'. Have no idea how to tweak Norton. Cheers, William.

Don't worry about it then, you would know if there was anything to adjust by your results from the test.
