How to check the MAC address of hub and all devices connected to it?

[Joshua Goi]

Hi,

How do I check the MAC address of the network hub I'm connected to and all other network devices connected to it?

And how do I check for the IP address for the same devices? Thanks!

Hi Joshua,

Try "arp -a"

do man arp for more help on this command.

Hope this helps.

ping the network address.
ping a.b.c.0 if Class D
ping a.b.0.0 if Class C...

then do arp -a.

The hub may not have a MAC or an IP unless it is a managed hub.

You can use a ping to try and get them to responds then use arp -a to see them but this is not totally reliable.

Better to use something like getif (for WindowsNT/2K/XP)

and use its IP Discovery to sweep the range of possible IP addresses and see what comes up. Then look at the arp.

If it is a managed hub, and the hub itself has an IP address, you *MAY* be able to telnet to the hub itself and have it display its arp table or port list. It may be able to show you the MAC addresses and *possibly* (no guarantee though) IP addresses of everything that is conencted to it.

This is *highly dependent* on the hub you have though. If it is a $30 hub from CompUSA or something, you will probably be out of luck.
