Please help - one technical question...

Hello all,

I have one technical question that I don't know to solve,
please advise:

Scenario:
We send ICMP echo packets to a targeted computer and to
receive the ICMP echo reply packet if the targeted
computer is online. This can be done by using PING
command. After issuing the PING command, we can issue the
ARP command to check the Ethernet address that has been
cached in our computer, thus establishing the IP address
to Ethernet Address correspondence. But this approach can
only handle single computer. For multiple computers, we
will have to do it one by one and the process will be
slow to scan ALL the computer in the LAN segment near us.

We want a efficient solution for the above scenario, can
you suggest one?

Are there any tools available?

Pleae help. Thanks a lot.

yes... buy a Cisco router and let it do it automatically for you

why in god's good name would you want to do this anyway? there can be no
real purpose unless your employer gave you this task as a make work project

The ONLY reason I can think that you are even doing this is for DHCP static
addressing... so here are a couple of solutions:

1. download a network scanner (etherpeek is one I think)

2) create a script that will do it for you

3) check network documentation - SURELY there must be some!!
