Additionally, many DHCP clients send a host-name included in their DHCP request, so the DHCP server has a name for this device, even if that name does not appear anywhere else (DNS, SMB, …). Your DHCP server knows both of them since it has assigned the IP addresses. The only reliable information that you have about hosts in your network is that they have MAC and IP addresses. Scanning the whole port range with -p 0-65535, while generating a significant network footprint, will still not show hosts that simply don't have any open ports. Nor will any hosts that don't offer services on the ports that you scan using the -p option. Hosts that block ping probes will not appear in the output. Nmap scan report for device2.local (192.168.4.2) Nmap scan report for device1.local (192.168.4.1) Nmap -sP does reverse DNS lookups, so if your devices have reverse DNS entries, its output looks like this: > nmap -sP 192.168.4.0/24 ![]() Unfortunately I don't have access to a Raspberry Pi at the moment, so everything displayed here comes from my Debian 7 box. I think you need to be more precise about your problem, especially the definition of a device name. Nmap done: 256 IP addresses (14 hosts up) scanned in 49.30 seconds I want a list of names of all devices connected to my Wi-Fi network via the ~ $ nmap -sP 192.168.4.0/24 I can get it also on some applications so I guess it can be done in some way. I've already tried without great success many commands found on the web, but nothing worked like I wanted to.īasically, when I enter my router settings, I can get the devices' names that are connected to my net. I wanted to know the names of all the devices on the network. ![]()
