How to determine an
IP address.
Issue:How to determine an IP address.
Solution:Note:
This document contains
information about determining your own IP address. If you're
looking for information about obtaining an IP address of another
computer or a website see document
CH000962.
Microsoft Windows Users
- Click Start / Run and type:
"command" (without the quotes) to open a
MS-DOS
prompt.
- From the prompt, type
"ipconfig" (without the
quotes) and press enter. This should give you information
similar to what is shown below.
Windows 2000 IP Configuration
Ethernet adapter Local Area Connection:
Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 192.168.1.101
Subnet Mask . . . . . . . . . . : 255.255.255.0
Default Gateway . . . . . . . : 192.168.1.1
As seen in the above example, the IP address as well as other
important network information is listed when using the
"ipconfig" command. If you have more than one network
adapter, e.g. a wireless adapter and network adapter you'll see each
adapter listed when using this command.
Home network and corporate network users
This information is the IP address of your computer
in your network. If you're computer is connected to the Internet the
IP address shown in this screen will more than likely not be
the IP address other people and web pages see. To determine this IP
address easily see the below online service section.
Graphical representation of network settings
Microsoft Windows XP users may get a
GUI representation of their
network by right-clicking the network icon in their
systray
and selecting "Status". Within the "Local Area
Connection Status" window click the "Support" tab.
Microsoft Windows 98 users may
also get a GUI representation of
their network settings by clicking Start / Run and typing
"ipconfig" in the run line. Unfortunately, not all versions
of Windows have this feature.
Linux / Unix, BSD 4.2+, and Apple OS X,
Operating System Users
For Linux or Unix users, to view their IP address or network
information, users must have administrator or root privileges.
- Open the Linux or Unix shell
if you are utilizing a GUI interface for your Linux or Unix
machine.
- From the prompt, type
"ifconfig eth0"
(without the quotes) and press enter. This should give you a
listing of network information similar to what is seen below.
eth0 Link encap:Ethernet HWaddr 00:A0:24:72:EB:0A
inet addr:10.10.10.2 Bcast:10.0.0.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:5569799 errors:32 dropped:32 overruns:0 frame:6
TX packets:3548292 errors:0 dropped:0 overruns:0 carrier:3
Collisions:14
Interrupt:18 Base address:0xda00
As seen from the above example, users will commonly see the
network settings for all their network devices when running the
"ifconfig" command. First in the above example we have the
network settings for the "lo" or "local
loopback", next is the actual network settings of your network
adapter.
Home network and corporate network users
This information is the IP address of your computer
in your network. If you're computer is connected to the Internet the
IP address shown in this screen will more than likely not be
the IP address other people and web pages see. To determine this IP
address easily see the below online service section.
Apple Macintosh Users
- From the Apple menu,
select the "Apple System Profiler"
- Open the "Network overview"
- Open "TCP/IP"
Within this window the user will be able to see the computer's
network information including the IP address.
Home network and corporate network users
This information is the IP address of your computer
in your network. If you're computer is connected to the Internet the
IP address shown in this screen will more than likely not be
the IP address other people and web pages see. To determine this IP
address easily see the below online service section.
Online services
When behind a network
router and/or using a network
proxy your IP address will
not be same as what you see when following the above steps. To
easily determine what your IP address is as seen by other people and
web pages on the Internet we suggest using one of the below online
services.
