TTinco - How do you find out what your IP address is?

[Buzzsaw]

I'm sure there is a way...can you give us the keystrokes?

 

[lander]

buzz,
open a DOS Prompt and type

ipconfig

 

[lander]

you should see results like

Windows 2000 IP Configuration

Ethernet adapter Local Area Connection:

Connection-specific DNS Suffix . : XXXX.XXX
IP Address. . . . . . . . . . . . : 555.55.55.555
Subnet Mask . . . . . . . . . . . :
xxxxxxxxx
Default Gateway . . . . . . . . . :
xxxxxx

lol, the generals way is easier.

 

[lander]

yeah, or you can go to Cascade .. they show you your ip for "fraud prevention"

 

[Buzzsaw]

Thanks guys...

When you signed in at Securebuxx your IP # always showed up......

Never mind.

General,
Your web site gives the IP being used to access the net. If you go through a proxy then this fails.

Say your IP is 123.45.6.7
Say you use a proxy server 999.99.9.9

ipconfig with say your ip is (and rightly so) : 123.45.6.7

www.whatismyip.com will say your ip is : 999.99.9.9 (that's not your IP that's the ip of the proxy server being used).

that said - most people (not named Butchy) do not proxy, so that site will be fine for 99% of you.

TTinCo and Lander-

You both have hit on something that needs a little clearing up.

TTinCo's ipconfig (or winipcfg on Windows 95/98/Me) shows the address of your machine. If you are behind a firewall or corporate network, that may be a "local network" IP address.

Lander points out that the address of the "proxy" server (if your ISP uses one) is the address that the rest of the world sees. Small correction on your 99% proxying claim: AOL is pretty much all proxy. When you dial into AOL, you get routed through their proxy servers. It's so weird in fact, that if check out your IP address on that whatismyip site, it can change over the course of an hour.

What this www.whatismysip.com site shows is the same address the sportsbook would see.

Thanks Java,
I'm behind a corparate firewall. I have an internal IP, given by the DHCP server.

How do I see the IP that is actually being used externally to access the web? (without going to whatismyip)

Thanks.

 

[Java]

Lander-
Not sure. I created a similar IP message on my own site (that does what whatismyip does). You might try traceroute for some other interesting information. From the DOS prompt:

tracert www.yahoo.com

This will show path you take getting to yahoo. If there are problems with the traceroute resolving DNS infomation, use the -d option which will just show IP addresses (and runs faster).

 

[TTinCO]

Lander, your IP will most likely show up as the ip of your company's gateway to the internet (firewall\router).

Type ipconfig & the gateway will be what your IP shows up as to the outside world. This IP will be the same for everyone at your office.

That will hold true unless you have an internal router between you and the actual gateway.

 

[lander]

Somehow they block tracert & ping.

They can resolve DNS lookup, but everything times out with those two commands.

 

[TTinCO]

That means that your firewall is blocking ICMP traffic.

No way around that one....

 

[lander]

We must have an internal router, because the Gateway IP is not what the outside world is seeing.

Thanks for your help guys - I was mostly curious. I'm a total square when it comes to the networking side of things.

I do have secure HTTP tunnel set up - that keeps me going

 

[lander]

one last question for the network gurus -

what do these do :

Primary WINS Server . . . . . . . :
Secondary WINS Server . . . . . . :

 

[Java]

TTinCo-
Lander almost guaranteed to have local area network with an internal 10.x.x.x address or 192.x.x.x address. The side of the router/firewall he sees will be one of the internals.

Lander, I guess you are stuck with the whatismyip site (or you could ask one of the techies and explain it's to answer a question on a sports wagering forum during working hours).

 

[lander]

Java they don't even know I'm on this site ... I forward all my http connections through a SSH connection on port 80

They see a single secure connection to NYC Roadrunner

when they do a Netstat.
keeps me out of trouble

it's starts with 172.xxxxxxx

 

[Java]

Lander-
Oops, I left that one out. Here is the info on the reserved, private, internal IP address.
Class A: 10.0.0.0 to 10.255.255.255.255
Class B: 172.16.0.0 to 172.31.255.255
Class C: 192.168.0.0 to 192.168.255.255

No address in this range can be used as an external IP address on the real internet. These addresses are reserved for local networks or some wider networks within a company, but not to the outside world.
