    nmap -sn 192.168.1.0/24

    Put your network number in it. It'll do a ping-sweep of your network and report the reverse DNS's of the up machines. Won't find down machines.

    C:> for /L %N in (1,1,254) do @nslookup 192.168.0.%N >> names.txt

    That'll do a reverse lookup of every IP in your subnet.

  2. Try using this simple command prompt code. To get all the network ips arp -a to find where an ip is coming from tracert "ip"

  3. Using Powershell - dmitrysotnikov wrote a nice function, this is from: http://dmitrysotnikov.wordpress.com/2008/03/07/get-computer-by-ip-address/

    does need some error handling for cleaner 'time-out' and 'host not found' replies.

    function Get-ComputerNameByIP {
param(
$IPAddress = $null
)
BEGIN {
}
PROCESS {
if ($IPAddress -and $_) {
throw ‘Please use either pipeline or input parameter’
break
} elseif ($IPAddress) {
([System.Net.Dns]::GetHostbyAddress($IPAddress))
} elseif ($_) {
trap [Exception] {
write-warning $_.Exception.Message
continue;
}
[System.Net.Dns]::GetHostbyAddress($_)
} else {
$IPAddress = Read-Host “Please supply the IP Address”
[System.Net.Dns]::GetHostbyAddress($IPAddress)
}
}
END {
}
}

#Use any range you want here
1..255 | ForEach-Object {”10.20.100.$_”} | Get-ComputerNameByIP

  4. If you want to go for "regular", nmap will do just fine.

    If you want to go for "obscure", Doxpara Paketto Keiretsu will do that with scanrand and friends. Not exactly "offical" tools but certainly useful for finding nodes you can't otherwise see. And did I mention it's fast?

  6. There is a tool i like to use especially when i'd like to find a free IP in the chaos i like to call my network. It is called IP-Tools by KS-Soft and does @sysadmin1138s suggestion graphically. It has 18 other great utilities as well. It is a great little swiss army knife

  7. May help:

    If you do have a server name and want to look up the IP for it (vice versa too), use cmd => nslookup "put your server name here"
