how do I get my "external IP address"?
I am trying to find out my external IP address. Also I probably have a few misconceptions as to how ISPs and IP addresses work. First of all I connect to my ISP with DHCP. Currently when I check my IP address I see that my IP address is 10.200.18.159. This is a private IP address. These addresses are private and not accessible from the internet from my understanding:
(10.*.*.*)
(172.16.*.*) through (172.31.*.*)
(192.168.*.*) through (192.168.255.255)
So this means that my IP (10.200.18.159) is an address on my ISPs private lan.
My major question is this: do I have an "public IP address" also? In other words; if I were to go to a different machine, outside of my home network, could I type in an IP address into a web browser and reach that machine (assuming I have a web server running)? I tried this one site that claimed it could tell me my address:
I guess the strange thing is that if I run a traceroute to any site I get this for the first few addresses:
1) 10.200.18.1 (I am assuming a gateway or proxy of my ISP)
2) 216.157.205.250 (the mikrotik website)
3) 10.200.1.1 (I am assuming a gateway or proxy of my ISP)
4) 63.89.180.254 (no idea)
5) 64.186.46.5 (no idea)
Is this maybe some technique that they use to mask my "external IP" address from me? Am I misled in believing that there is such a thing as an "external IP address"? I don't know all the inner workings of TCP/IP. But I am assuming that there is not a persistent connection. In other words; a client sends a request for a web page. The ISP does name resolution using a DNS server and forwards the request to the server that has the page. Does the web site then send out the page with the clients IP address (in which case the client would have to have an IP address that is accessible from the internet)? Or does the server simply return it to the ISP and the ISP handles getting it back to the client?

As you've seen, your "internal" IP is different to your "external" IP.
This happens because ISP's pool the IP addresses at a main router, and use that router to send out the requests for however many customers are connected to it. This means that the external IP address is the IP address of the ISP's router, and your internal IP address is the IP address of your machine that was assigned by the router so it knows where to send the data to so that it reaches your machine.
At a guess I'd say that when you vist your external IP, you see a website that's not associated with anthing of yours because your ISP is using that IP address to host websites as well, and that just happens to be the "default" site for that IP address, so that's what's shown.
In this scenario, you can't connect to your PC directly from outside your network, meaning that a normal computer can't connect to it through the internet.

The easiest way in case you just want to know your public IP address is type in "my ip address" in Google and search. This will display your public IP address.

Welcome to DevShed Forums, bellze.
Please don't ask a question that's only loosely related in someone else's thread. (I'll split this into a new thread later.)
192.168.1.1 is a private/internal IP address. It's often the IP address to the internal-facing port of a router. An "external IP address" (typically a public IP address) would be the address of the external-facing port of your router (e.g. the port connected to a cable modem).
