Hi, What is the problem with 17 million pings? If you turn of DNS resolution it will be quite fast, even on a 10 mbit LAN. Don't use broadcast pings: you don't know where the subnet boundaries are and therefore won't be able to know the broadcast addresses. If it really is a /8 network (i.e. flat, which I doubt) then you could use broadcast pings, but please note that: A: not all devices that respond to ping respond to broadcast ping B: you will miss replies due to the fact that many devices will answer simultanesouly You might also want to manage expectations. Pentesting a full class A, even given low population of the network will take you months. I think what you really want to do is a vulnerability scan. Just that part, running nmap and nessus on a full class A will keep you busy for a while :-) Just make sure the client is aware that not all IP's on his class A will be hit. --Ralph -----Original Message----- From: John Thomas [mailto:mjohn2000_99 () yahoo com] Sent: 08 February 2005 17:42 To: pen-test () securityfocus com Subject: Mapping Class A network ( any easy trick?) --- Virus checked / op virussen gecontroleerd --- I am about to do a penetration testing on a "Class A network" and wondering how I can map the network without pinging 17 million IPs.(nmap -Sp 10.0.0.0/8) I did some research and the best information I got is from one of the earlier post on this list(http://seclists.org/lists/pen-test/2004/Jul/0067.html) . It was to use broadcast IPs for pings. But it may miss some subnets. Is that the best way to it?
