nslookup comes with Windows. To get "dig" you need to install the Windows port of ISC BIND

Another useful one for finding other blocks owned by the same provider is http://bgp.potaroo.net/

Short bash script for looking-glass. Run as "scriptname ipaddress":

#!/bin/bash
firefox -remote "openURL(http://looking-glass.optus.net.au/cgi-bin/nph-looking-glass.pl?query=bgp&addr=$1&BGP_Tabl e=International&DIG_Table=ANY,new-tab)"

Windows cmd file version

@echo off
cd path-to-firefox
firefox -remote "openURL(http://looking-glass.optus.net.au/cgi-bin/nph-looking-glass.pl?query=bgp&addr=%1&BGP_Tabl e=International&DIG_Table=ANY,new-tab)"

Applied to 65.19.129.18 gives you AS6939

Once you know the AS number, you can use this one to get the BGP path from Telstra to the target. Run as "scriptname asnumber"

#!/bin/bash
firefox -remote "openURL(http://bgp.potaroo.net/cgi-bin/as-report?as=AS$1&view=1221,new-tab)"

or

@echo off
cd path-to-firefox
firefox -remote "openURL(http://bgp.potaroo.net/cgi-bin/as-report?as=AS%1&view=1221,new-tab)"

Applied to 6939 gives you a long list of adjacent networks and about 50 IP blocks advertised by Hurricane.
