Idenitify a device by IP

By KingOfTheNerds ·
Hi All,

I have an IP address on the network that when i go to my browser and type it in, it asks for login information and password.

I would like to know how do i identify this computer. The IP is 192.168.1.31 and we have a DHCP scope for everything between 192.168.1.33 - 254.

So i am wondering what this device is?

Is there some kind of command that allows me to identify the device by simply knowing its IP address?

Thankyou

Hi,

This sounds like the router access for setting it up, particularly since it is asking for user Id and password.
Check router documents for factory defaults.

If your DNS server has Reverse lookup setup then typing 'ping -a address' it will return the DNS name of the device, assuming, it has a dns entry. If not then its probably a router of some sort.

try this command
nbtstat -a 192.168.1.31

note:
NBTSTAT
a break after nbtstat and
a break after -a

I tied this but it replied:
host not found

Is this because the IP is out of the Scope of the DHCP server. I have 192.168.1.1-32 out of scope for static IPs. Thats why i am having trouble identifying what it is. I have around 13 switches in the school so i don't know which one it would be.

I have checked all the DHCP addresses and Static addresses and only found one browser interface to our main switch which is a HP ProCurve 4000M, i have an Allied Tynsen and the others are all Netgear 24 port switches.

Maybe the address i am finding is to the Allied Tynsen, but why can't i find the other switches in the browser?

The follwoing will only tell you what type of device it is, but that should give you a clue.
1. Ping the IP address.
2. at a command prompt type arp -a
This will display the arp table, from there take the MAC for the IP address and look it up at (remove spaces):

or:

once you know what device it is it should be much easier to identify.
Hope this helps.

Thankyou, I used this and discovered the manufacturer of the device which was ALLIED TELESYN INT which means it was the Telesyn switch after all.

The only problem now is how do i get in to the switch? I guess i will just call the manufacturer.

Thanks again
