I'm looking for a command line tool which gets an IP address and returns the host name, for Windows.

The command you are looking for is called nslookup, works fine for reverse lookups IFF someone has configured a reverse zone file, which they don't always do.

if all the above fails, and you are specifically looking for a Windows machine, you can use
nbtstat -a 192.168.1.50
The data returned will be all the NetBIOS records the machine has. The one with a <20h> record type will usually be the machine's name.

@Flextra - you will need SMB access to the machine. Your VPN may be blocking it. – Moose Apr 7 '16 at 2:55

Interesting, looks like it tacks on the fully qualified domain name in the formatting:
Pinging NETBIOSNAME.DOMAINNAME.com [xxx.xxx.xxx.xxx]. If its on the network and not on the domain (for me a unix system of interest) thenping -ajust formats with the ipaddress alone it looks like. – jxramos Feb 6 '17 at 21:12 -

For many IP addresses you could just use ping -a, for example
ping -a 209.85.229.106
will return
Pinging ww-in-f106.google.com [209.85.229.106] with 32 bytes of data:
Reply from 209.85.229.106...........

If you use nslookup command with the IP address as its first argument will return the PTR record (the reverse entry) if it exists. For example:
nslookup 192.168.1.50

Use dig. A Windows port is available from the ISC here (look in the immediate download box for the link to the zip file). Here's their man page reference for dig.
Ward's point about the reverse lookup records often not getting created is very much true. Reverse lookups often do fail because many admins don't bother creating the ptr records.

(tested under Windows 10 x64)
From command line:
FOR /F "tokens=2 delims= " %A in ('2^>NUL NSLOOKUP "%IP_ADDRESS%" ^| FINDSTR /C:": "') do ECHO %A
Within a script:
FOR /F "tokens=2 delims= " %%A in ('2^>NUL NSLOOKUP "%IP_ADDRESS%" ^| FINDSTR /C:": "') do ECHO %%A
Two (side)notes:
- To supress
NSLOOKUPerrors you have to use2^>NULinstead of1^>NUL - I've used
FINDSTR /Cto extract the value after the four whitespace characters. As the four spaces only seem to exist for theName:entry, this appears to be only way to make it work on other localized systems.

if you want to know the host-name in same network then please use another machine which have same network and use below commend
Ping -an ip addres
