What's my real IP?

I just got this new LAN connection to the net. Basically, my new ISP gets a leased line and divides it among the users using a switch. He's also using a bandwidth-limiting software (which I guess is some kind of a proxy) that limits the bandwidth to 64 kbps. Ipconfig shows me the following:

Windows IP Configuration
Ethernet adapter Local Area Connection:



Connection-specific DNS Suffix . :

IP Address. . . . . . . . . . . . : 90.0.0.72

Subnet Mask . . . . . . . . . . . : 255.255.255.0

Default Gateway . . . . . . . . . : 90.0.0.1

My question is how do I find out what my IP on the Internet is as 90.0.0.72 is obviously the internal LAN IP. For example, if I were to have a web server on my computer, what address should I tell people to go to?

Go to www.whatismyip.com

It will tell you your true ip... or the ip that your proxy is using.

if you use a proxy, www.whatismyip.com may not work.

Try doing a simple: C:/netstat -a

and then the ip address to the left is yours, regardless if you use a proxy or not.

Phishphreak: That whatsmyip.com IP is the IP of the proxy, which isn't what i want. What I want is the IP that another guy on the net, say you, would use to access my computer.
WebCarnage: I already tried a netstat -a, and it shows 90.0.0.72 as my IP.

interesting configuration,

perhaps you should try a site like shields up and see what ip it thinks you have.
or
send a file to someone using p2p, and get them to netstat -an, and see if your ip shows up.
or?
quiery the gateway router and try to get the ip's of the interfaces open.
just a thought...

When I used to have this problem I would just sign onto IRC and do a /dns <my nick> without the <> of course and that usualy gave me the correct Ip. Not sure if it will work of you but has for me in the past

cgkanchi,

Go to Start/Run ant type "command" to open dos "DOS" prompt (i think you already know this reading above). There type "ipconfig" and the first address under the second Ethernet adaptor is your IP for Internet in that moment.

Hope it helps you.

Bye.

The ip address given by myipaddress.com is what others on the internet see you as. To reach your computer they would have to find a way through or arround it to get to your internal machine. Depending on what kind of trafic the proxy, router or firewall lets in would be the first step to determining the way into the internal network.

I read your post !
I had an thought on the true IP of yours. The info that you gave is an DNS type IP suffix.How ever from reading your subnet mask numbers which puts you to be in the same network segment as your DNS Suffix.So your networking IP addres for your "puter"has to be in the same range as long as your LAN is not behind an NAT.In your starting DNS IP Suffix which you are stateing to be 90.0.0.72<--DNS IP in your case.With subnet mask 255.255.255.0 <--- Which is not subneted in your LAN case.In this case i think your ISP has asigned an Dynamic DNS server to obtain IP's for your network DNS.Anyhow your true IP Suffix is in this range 90.0.0.2 to 90.0.0.254 which are dynamicly set trugh your DHCP server in your LAN case that would be your 90.0.0.1 IP.The last octate that is nr 1 is usually your Gateway/DHCP.With the Win2000 server there is 2 ways that you can obtain your true IP one is from your DHCP the other is tru your DNS server see fig. Under Example1http://www.microsoft.com/windows2000...abilityDns.htm
So there fore what you can do is to get your true IP look up your computer hostname.Ex. in command prompt in win9x type, winipcfg or ipconfig/ALL or in win2000 command type ipconfig/ALL then look at your Computer Host name..Then again at prompt type in your computer host name yada.yada.somefing and ping it EX--> c:\>ping yada.yada.somefing <Enter>
to get saying this
pinging yada.yada.somefing [0.0.0.0]<----Your true IP

if you do that on a ptlink/hybrid irc with services it gives you your masked ip, so that wouldnt work. However on an irc without masked hosting, all you need to do is type /whois nickhere it gives you the same results.... the /dns command works the same way except for only giving you your ip not time of connection etc.. even though thats off topic... basically i agree with whomever said that above about netstat -an and sending the file, that would work yes. you can write scripts fairly easily or download scripts that go through all that and give your ip.. google it if you want more information. dunno, ask someone who knows more about bandwidth uncapping and they will surely be able to tell you how to figure it out with that type of setting. I guarendamntee you however that your gateway contains the correct information. so find the ip of that, and scan it for broadcasts, see which one has the same activity in which you have going down, and thatll tell you.

Ok, here's the status on the IP thing, any program that I run on my comp, including ipconfig and grc's ip agent tell me that my ip is 90.0.0.72. However, any command run remotely, ie a file transfer or a /dns on irc gives me the address of my ISP's proxy. How do I know that? I installed a web server on my comp and ran http://hostname and that worked as did http://90.0.0.72 but http://xxx.xxx.xxx.xxx (The /dns address) didn't work. So any more ideas??

im not sure what your asking cg, do you want those outside your proxied network to be able to reach your web site?

the dns server is not a web server so all you'll get from there is a page not found error 404

you say you can see your own page from your own computer...are others not on your network able to se it?? im confused

is everyone just typing the same garbage to get posts??? the guy doenst want fuc*** lan IP.. everyone knows how to get that.. he wants the wan IP. nooo ipconfig won't do it..noooo netstat -a won't do it... netstat -an etc.. bad advice.. noob responses im getting bored of.

If you had access to the proxy server you could make it foward connection attempts on port 80 or whatever else to you computer on the lan. I set up my switch on my cable network to foward specific trafic to specific machines. Also your isp may have a policy against running servers such as http and ftp without leasing a buisness line.

OK, I don't have access to the proxy (if you mean admin access), though my comp can obviously access the proxy, so I have that kind of access to it. Also, as much as I appreciate all the help, I am not a complete newbie, so please don't waste your breath telling me to run netstat or go to a site like whatismyip.com, because I'd already tried all that before I came here. Any methods to find out what proxy my ISP is running would help a lot, because then I could look it up.

If you are so bored, theres the door. At least they are making a attempt at answering the question. Posts like this will make your stay at Antionline a very very short one.

And by the way, who are you calling "Noob"? With your whole 5 posts and that bright shiney "NEWBIE" status under your name?

Lighten up. Contribute positively, or dont contribute, sheesh.
:rolleyes:

I don't know what is your operating system but if u have windows installed u can try to type:
c:\windows>winipcfg

Try!! :)

The only way that I know of for someone outside the network to access you computer through the proxy is to have admin access to the proxy or to find out what kind of trafic and what ports the proxy is letting inbound trafic come through. a way to do this ( if its ok with your provider ) is to port scan it then try sending packets through. The only prob with this is you cant ( that i know of ) direct the packets to your machine. To find out what proxy is running try to connect to the proxy and get the banner. again only do this if it is ok with your isp.

Try this in a ms-dos box

tracert www.antionline.com or your favorite website.....

You may see your IP address....

Another site is www.grc.com and use test my sheilds

Are you saying that your true IP by means is not what i posted in my preavious message where your network is an win2000 server enviroment.?? I know that your true IP is done that way..

OK, one lousy portscan did the trick, sorta. I now know that he's running xxx firewall and that it uses NAT (Network Address Translation) to do a single address assignment. According to the product's site:

Quote:

---

Single address assignments allow a single official IP address to be used by a number of local hosts for out-bound only internet users. Single Address Assignments are usually allocated to internal ranges according to their priority levels.

But I still don't know how to redirect some of the incoming traffic to my comp. Any ideas?

Hello friends!
I registered here just to make this post. First of all, I want you guys to know that I just want to help the guy who started this topic. If he/she has already found the solution, it was his duty to post it here so that everybody (those still googling) may know what to do. If he hasn't, then I hope he"ll find it usefull too. Secondly, there's nothing wrong in being "noob". We are all noobs in some fields, at some point in life. We don't know everything. And we are always learning - at least we should, and not deny that. Thirdly, this is a VERY VERY simple thing, which every "not noobs" should know, and since this is a VERY old thread, somebody should have helped a LONG time ago. What's happening to us guys? Why are we becoming so selfish? If you are an expert in some field, why feel annoyed at some newcomer's innocent querry? Knowledge is for sharing. And sharing knowledge never lessens yours - it makes your knowledge worthwhile.
Anyway, much lectures - I know many don't like. I'm just 31, so I know. Let's come to the point...
If you have a static IP, then you don't have to dig through all that bullshit. cmyip.com, checkip.dyndns.org, and whatever was posted earlier in this thread is good enough for you to publish for your purpose.
If you have a dynamic IP, then you need not worry either. The solution is equally simple. You don't need to do any port scans. This is not anything illegal, and you don't need to do ANY illegal activity to achieve your goal. What you do need to do, is update the dns address of your site (or whatever you are trying to host in your machine). DNS is something which converts the name (like: www.supercoolsite.com, or mygreatestftpsite.com, or, ftp://thisismyuberpc.com, or, privatepcathome.something.net....etc.etc). into a machine-understandable thing (like: 210.224.xx.xx etc). So, every time you start your server, you should already have updated that new DNS. That's it. Nothing more. It's that simple. If you already knew this, then you should have found the solution ...
How do you update your new IP? It's even simpler. There are many sites/ways, but you need only one, right? So here's what I suggest. I hope you already know about domain names, since you ARE hosting a site. If you have bought one, cheers! If you want one, you can get it for FREE at dyndns.org. There may be others, but I haven't and didn't need to ... ;
Just go there and browse, and you"ll get it. But for idiot googlers, here's the easiest solution:
I hope you are intelligent enough to use Opera and not IE or any other similar sh!t. Firefox is OK, but not as secure as opera. However, there's more possibilities for advanced users(lol) with Firefox than with opera.
In opera, just get this widget: DynDNS Updater.
First you run opera and run this widget. Then your IP will be associated with the free dyndns hostname you registered for. Now run your server software and host your site. Enjoy!
Please note that there are of course, other sites which do the same service for your non-dyndns-hostnamed site. Please use the free, friendly service called GOOGLE for that. This is how I learned stuff. Searchlores.org? I found it through google. Thank you google. ***** Micr0sft and *****ing yah00. Fu*k'em hard!
Bye Bye friends. I won't be here again to read the scepticism and dirty responces from some sc*ms. If this post helps some newcomers (not n00bs), then enjoy.
BTW, I almost forgot...I"ll be as much an *ss-h0le as G.What-a-sh!t.Bush if I don't give the PROPER credits to http://lifehacker.com. Bye Bye!...

P.S.
I just clicked some absurd, made-up links I posted, and I found that they do exist!!! Sorry for that guys! I didn't intend to promote free ads for those scumbags... Hope you understand...
BTW, I do intend to let you know what I do love... RL-Team.net
I hope you"ll not consider this as advertise.... I love this site, and if you wanna know who I am, just search for someone with a ".1"...
Enough said...
I don't get anything out of this... much less money... but some love? YEAH! (not without thorns, though!):cool: See u there...

What you do need to do, is update the dns address of your site (or whatever you are trying to host in your machine).

At the risk of getting flamed (this being an old thread), I will point out that
you missed the point that his ISP was using a NAT router and assigning
him a private LAN address. Therefore, the only way unsolicited traffic
could reach him from the net would be for that router to be configured
to allow it. It's the same as having a popular home style router. You have
to configure port forwarding on the router if you hope to have your
server reachable from outside.

BTW, you are right, it would have been nice to know if he ever solved
the problem (by getting a new ISP, LOL).
:cool:

Yes, talk to the guy running that firewall/nat. It doesn't sound like they're using binat but a regular nat (outbound only). Then you run into the same problem everybody with a homerouter has when setting up a server.. The port needs to be forwarded..


Oh.. Doh.. I just now realised that post was made 5 years ago :drink:
