About finding IP address

how to find the IP address of our own system and others systems  when connected in the internet?

Type ipconfig (in Linux ifconfig) on command prompt / shell and you get list of your network interfaces.

type arp -a (in Linux only arp) and you get list of your arp entries. You could try to send broadcast ping to your sub-network and then use arp -a to seek out which machines answered to ping/ARP.
If you are looking to find out which IP addresses your machine has IP sessions with and which ports are open on your machine, use "netstat -an" at a command line.

What OS? Win95/98 -> winipcfg, NT/Win2K -> ipconfig /all, most unix -> netstat -in. As to the rest of your question, Im not sure what you mean by "others systems".

hai,
   your way of answering is very simple and easy understandable.
hmm... Let's say that your ip is 192.168.1.1 and subnetmask 255.255.255.0. you can scan all computer on your subnet by sending broadcast ping typing ping 192.168.1.255 on command prompt. Then type arp -a and you see every machine that answered in list.

There can be computers in network that doesn't answer to ping but they answer to ARP request and so you see them in arp entry list.
