Identifying Devices on a Network
Android IP scanners employ several techniques to identify devices on a network. The primary method involves sending network packets and analyzing the responses. This process, often referred to as “ping sweeping” or “network discovery,” allows the application to map out the network’s active devices.The core mechanism revolves around the Internet Control Message Protocol (ICMP) and the Address Resolution Protocol (ARP).
ICMP (ping) and ARP are the fundamental protocols used by IP scanners to identify devices.
Here’s how it works:
1. Ping Sweep
The scanner sends ICMP echo request packets (pings) to IP addresses within the specified range. Devices that are active on the network respond with an ICMP echo reply. The scanner then identifies these devices as being online.
2. ARP Request
The scanner uses ARP to determine the MAC address associated with each IP address. It sends ARP requests, and the device with the corresponding IP address responds with its MAC address. This association of IP and MAC addresses helps identify devices more accurately.
3. Hostname Resolution (Reverse DNS Lookup)
The scanner uses the Domain Name System (DNS) to perform a reverse DNS lookup. It sends a request to the DNS server associated with the network, asking for the hostname associated with the IP address. If successful, this helps to identify the device by name.
4. Port Scanning (Optional)
If the scanner includes port scanning, it sends requests to various ports on each IP address to determine if those ports are open. This information is valuable for understanding the services running on each device.By combining these methods, Android IP scanners provide a comprehensive view of the devices connected to a network, their IP addresses, MAC addresses, hostnames, and, in some cases, the services they are running.
