View Full Version : What is my IP address?

How do I find out what my IP address is? I've tried whatismyip.com, which gives me one number, and my modem gives two different numbers. Which of those three numbers is my actual internet IP address (or is there another altogether)?

I thought I'd be clever and figure it out by signing up with no-ip.com and checking what they think my IP address is compared with the little utility you can download from them to auto-update it every time you log on. However the no-ip.com website and their utility disagreed with each other.

Any suggestions?

Cheers,
Mike.

www.whatismyip.com will give you your true, external IP address.

Your router will tell you this, and also your internal IP address.

Which is correct? Depends on the purpose. An internal network related thing will involve your internal IP, which will start in 192.168.x.x, or 10.x.x.x.

An internet thing probably has to do with your external IP address, given by your ISP. In most cases in NZ this starts with 222.152.x.x (Jetstream), 60.x.x.x (Orcon bitstream), 202.x.x.x (Most dial-up), or 203.x.x.x (Telstra/Paradise).

Note I said in most cases. It really could be many others, but I have covered the majority.

Cheers George

No no no, that will give internal IP address.

I'm pretty sure he wants external (www.whatismyip.com)

Your router will tell you this, and also your internal IP address.whatismyip.com and my router did not give the same address. Neither of the addresses my IP gave were internal IPs (my internal IPs start with 10.1) - one started with 202, the other with 203 (my router told me my internal IP address somewhere else in the settings). whatismyip.com gave a 203 as well, but different from the one my router gave me.

Make sense?

No no no, that will give internal IP address.

I'm pretty sure he wants external (http://www.whatismyip.com)Correct, I'm after my true external IP address. IPCONFIG gives only my internal IP addresses.

OK Then.

http://checkip.dyndns.org/
http://www.whatismyip.com/
http://www.whatismyipaddress.com/
http://www.lawrencegoetz.com/programs/ipinfo/

Go to those four. Do they all agree? If not, something very strange is at work. You don't happen to have some rotating proxy program running do you!?

There should only be ONE external IP address, and both router and websites should agree.

What type of connection are you on?

Could be a transparent proxy on behalf of the ISP.

Run:
ipconfig /all
Post back the results and I'll let you know which line is your _real_ IP address :)

Huh?

How can ipconfig /all even know the real IP address?

Sure doesn't say it for me, I just get my 10.2.0.19 internal one...

Well, he starts off saying "Modem" then halfway through says "Router".

If its a router, then connect to the routers webmin interface and it'll tell you in there.

Yeah, but apparently that gives him two external IP addresses. Perhaps one is gateway or DNS?

Any chance of a screenshot Mike?

Well that's interesting. Last night whatismyip.com and my router's settings did not show the same ip address - they were quite different (in fact the whatismyip.com address had been listed as my ip address for at least the past week :confused: ). This morning, however, whatismyip.com and my router are reporting the same IP address (different to the one I've apparently had for the past week).

How confusing :)

It sounds like you're typing your command in the Run dialogue rather than a cmd prompt. Open the Run dialogue (Start > Run) and type in CMD and OK. Now you should have a CMD prompt where you can type in your commands and they shouldn't just flash on your screen for half a second.

HTH

My money is on a transparent proxy - most sites like "whatsmyip.com" etc are only able to report the IP of the proxy retrieving the page for you, rather than your machine directly.

Knowing what ISP he's with could help. And connection type - ADSL, Cable?

Thats not quite true. If you are running through a transparent proxy (as some ISP's do) then it will return their IP address.

Your real IP address is in the router somewhere. On mine it shows my static LAN IP and my actual WAN (or NAT) IP address. This is the real one.

Yeah, but the confusion is there when the router tells him a 202.* AND a 203.* IP address, both external NZ IP addresses :o

I think one of them might be his gateway or a DNS server.

It wont be DNS - DNS has nothing to do with this.
Gateway? Maybe.......

Proxy Server - Most likely!

Yes, sorry - one is labelled "IP Address", the other labelled "Gateway". I do find it interesting that yesterday (and for at least a week) the one labelled "IP Address" and the address given on numerous sites on the net did not match, however today they do. The one on different sites (such as whatismyip.com) for the past week hasn't changed until today, whereas the one in my router settings appears to change...? So do I take the one in the router settings as my IP address, or the one given in whatismyip.com?

Your ISP might have taken the cache out of the loop.
