[linux] How to get hostname from IP (Linux)?

I'd like to get remote machine/hostname through IP Address. I found lots of answer such as nslookup, host, resloveip, etc.. but I still can't get hostname from my target machine(cent OS, ubuntu etc...) It seems need to register to DNS server?

I have a machine named test and using IP 10.1.27.97

but I used the method above still can't not get "test"

Does anyone can help me to get the hostname form IP Address?

Another simple way I found for using in LAN is

ssh [username@ip] uname -n

If you need to login command line will be

sshpass -p "[password]" ssh [username@ip] uname -n

To find a hostname in your local network by IP address you can use:

nmblookup -A <ip>

To find a hostname on the internet you could use the host program:

host <ip>

Or you can install nbtscan by running:

sudo apt-get install nbtscan

And use:

nbtscan <ip>

You can query a name server with nslookup. It works both ways!

nslookup <IP>
nslookup <hostname>
