Seems not many were interested in replying to my previous post, "Ports".I thought no question was senseless or pathetic atleast from the mouth of a newbie,so i asked it.
Anyways,i just wanted to ask ive seen that when u put netstat -n it shows Local Add. as 127.0.0.1 when i use it at Dial up(at Cable obviously ill know it). So why does it show 127.0.0.1 is it because of the ISP or some other reason & how should one see his IP (using Command Line) if it shows 127.0.0.1 Thanks,
Urs in Health,

127.0.0.1 is the loopback go get a book on networking and find all this out for yourself :p

Quit playing with your own interface, you're gonna go blind if you keep that up.

an IP address is your internet protocol address, it's basically how the TCP/IP service runs on your computer. All current OS' use TCP/IP but Mac which uses AppleTalk (I believe).

All computers use 127.0.0.1 as a loopback, basically you can always count on that as being a dead address to anyone which points back to your computer no matter the OS.

Every address on the internet has a second IP for their computer, it basically signifies them from anyone else.

Forget about software buddy, what you need is to sit down and get comfortable with the IP protocol, and the entire TCP/IP protocol stack. If you want to spoof IP's then write yourself a program to do it. What's that? you don't know how? I guess you better start getting familliar with some programming language, C perhaps.

Blacknight u seem to be a genious & u proved me in my last post as well & great job that u told me 127.0.0.1 is a loopback else i couldnt have found it out in my entire life.God!.. i just wanted to ask that why does netstat -n show 127.0.0.1 as local add. for people who have dynamic IPs & same command shows the actual IP when used by people who have static IP.Why doesnt it show 127.0.0.1 on PCs which have conn. like cable.Maybe it does not happen but atleast ive seen this happening all time.Thanks,

I think the answer to that is that people with dial-ups are not always connected so if you try to look up ur IP while you're not connected, that is what you are going to get. On the other side, people with cable are always connected so whenever they look up their address it's going to be the actual IP and not 127.0.01, I'm not sure if that was your question though.

Another thing you have to understand, I'm not sure if you do or not, is that 127.0.0.1 is your local address no matter what kind of connection you have or don't have. If your computer does not even have a modem and it's never been on the internet, you will still have the same lookback. It really doesn't have anything to do with the internet. plus, you can also use localhost.localdomain as a hostname and it will go to 127.0.0.1, just like a real domain name like www.undergroundnews.com would take you to a certain IP address.

If it is due to the infrequent usage of Internet then what command should be used to find ones IP, i mean if netstat doesnt work for modem users & shows 127.0.0.1 Rather i put it simply, what command can be used to know ones IP? & regarding this Loopback,dont worry im clear with it, i wrote it coz im sick of Blacknights replies.

took some time filling it out...so hope this helps...

Macintosh

Mac TCP Go to the Control Panel, click on Mac TCP, your current IP Address should appear above the More button. TCP/IP Go to the Contol Panel, click on TCP/IP, your current IP Address should appear in the middle of the screen.


Windows 3.1

After starting Trumpet Winsock some information will appear on the screen. Your current IP Address will be among the information presented, usually at the bottom of the screen. It will say
'My IP Address =......'. This number is your IP address.


Windows 95/98

Click on the Start button, click on Run, in the box marked Open, enter: winipcfg, click on the OK button. A dialog box marked IP Configuration will appear that will show your current IP Address.


Windows NT /2000

Click on the Start button, click on Programs, click on Command Prompt. At the prompt enter 'ipconfig', press the Enter key. Your current IP address will show on the screen.
Or, for more detail, ipconfig /all :
C:\>ipconfig /all


Linux

At your shell prompt type ifconfig, which will result in output that will look very similar to that shown in the following screen dump, which shows the output from a two NIC Linux machine where eth0 is attached to an NTL Cable Modem and eth1 is attached to the internal network. Note that there is no indication here as to eth0 having obtained it's address via DHCP.

on the command line:
ifconfig eth0
This is of course, assuming you are connecting via ethernet to your ISP through DSL/Cable. You could just type "ifconfig -a" and everything you ever
wanted to know about your network interfaces will be shown...


AS/400

Use the WRKTCPSTS command of OS/400 to get
the address.


X -windows
goes like this as command promt
ifconfig eth0


Solaris

ifconfig -a ,will tell u all the possible network interfaces configured on the system.
check for inet value that is the ip value for the system.


Netware

userlist /a or nlist users /a will =
report the segment:macaddress of the currently logged in users

Correct me if im wrong anywhere...im no pro at this coz i jus searched up myself


"it is the question ...that drives the answer..."
