asked on
batch file to find hostnames from ip addresses of lot of machines
I need to find the hostnames from ip addresses of almost 50 machines. So I need to open a dos window and
issue ping -a ipaddress and then I get the reply form where I can get the ip address
like this
__________________________ __________ __________ __________ ________
C:\>ping -a ipaddress
Pinging hostname [ipaddress] with 32 bytes of data:
Reply from ipaddress: bytes=32 time=2ms TTL=122
Reply from ipaddress: bytes=32 time=2ms TTL=122
Reply from ipaddress: bytes=32 time=2ms TTL=122
Reply from ipaddress: bytes=32 time=2ms TTL=122
Ping statistics for ipaddress:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 2ms, Maximum = 2ms, Average = 2ms
__________________________ __________ __________ __________ ________
Now could somebody write a batch file for me which will be
batchfile inputfilename outputfilename
int the input file I will put all the ipaddresses
In the output file it should have the output as
ipaddress hostname
10.555.55.55 hostname
issue ping -a ipaddress and then I get the reply form where I can get the ip address
like this
