Calin's Humble Scanner - User Guide

## Scan method IPv4 Ping Broadcast

This method will find all IPv4 enabled hosts that responds to a ICMP Echo Request packet sent to a broadcast address.
`CHScanner` will build and send a single packet and all IPv4 enabled hosts that listen on the specified address will reply.
I have received responses from the following hosts:

- Allied Telesyn xxxxxxxxxxxxx
- Allied Telesyn xxxxxxxxxxxxx
- Allied Telesyn xxxxxxxxxxxxx
- HP xxxxxxxxxxxxx
- SMCxxxxxxxxxxxxx - responds with address used as Echo Request destination
- Xerox xxxxxxxxxxxxx
- Xerox xxxxxxxxxxxxx

To specify a destination address set it as :

- if empty, 255.255.255.255
- B for 255.255.255.255
- L for the broadcast address of the scanning host
- H for 224.0.0.1 - All Systems on this Subnet
- R for 224.0.0.2 - All Routers on this Subnet
- user specified IPv4 address

When the destination address is an IPv4 multicast address, the destination MAC address will be set as described in RFC 1112. In all other cases, the destination MAC address will be set to FF:FF:FF:FF:FF:FF.

For this method the Operating System Mimic does NOT obey the ID field of the ICMP packet.
