This is another method to get the hostname from the IP address. Run the nslookup command with an IP address from which you want to get the hostname. This command works a bit differently from the ping command that is discussed above. See the syntax to run on command prompt (CMD).
Using the command promptFrom the Start menu, select All Programs or Programs, then Accessories, and then Command Prompt. In the window that opens, at the prompt, enter hostname . The result on the next line of the command prompt window will display the hostname of the machine without the domain.
A far simpler and more common way to look up the hostname from an IP address is to use nslookup. Nslookup is a command-line utility, similar to dig, but that allows users to query DNS for hostnames and IP address mappings. 110.223.58.216.in-addr.arpa name = mba01s08-in-f14.1e100.net.
Use nslookup
nslookup 208.77.188.166
...
Non-authoritative answer:
166.188.77.208.in-addr.arpa name = www.example.com.
You can do a reverse DNS lookup with host
, too. Just give it the IP address as an argument:
$ host 192.168.0.10
server10 has address 192.168.0.10
Another NS lookup utility that can be used for reversed lookup is dig
with the -x
option:
$ dig -x 72.51.34.34
; <<>> DiG 9.9.2-P1 <<>> -x 72.51.34.34

Quoting from the dig manpage:
Reverse lookups -- mapping addresses to names -- are simplified by the -x option. addr is an IPv4 address in dotted-decimal notation, or a colon-delimited IPv6 address. When this option is used, there is no need to provide the name, class and type arguments. dig automatically performs a lookup for a name like 11.12.13.10.in-addr.arpa and sets the query type and class to PTR and IN respectively.
For Windows ping -a 10.10.10.10
For Windows, try:
NBTSTAT -A 10.100.3.104
or
ping -a 10.100.3.104
For Linux, try:
nmblookup -A 10.100.3.104
They are almost same.
