从 ip 地址获取本地主机名，即 Windows 10 上的 192.168.1.x python 3

Question

currently using:- import socket

hostip='192.168.1.62'
getip=socket.getaddrinfo(hostip,port=22)

returns info but does not include Hostname. seems to be a local DNS problem from other discussions. The local router finds all hostnames.

Answer 1

Hostname is only maintained by windows or netbios, so from a command prompt it is virtually impossible to find. So I switched to searching for the ip address by referencing the Mac address. The best solution so far is to use nmap and parse the results. My code for ip addresses up to 192.268.1.99 is this

mac='0a:0b:0c:0d'
arpin=os.popen('nmap -sP -n 192.168.1.0/24',"r").read()
arl=arpin.split("\n")
fmac=[arl.index(i) for i in arl if mac in i]
fip=arl[fmac[0]-2][-12:]

fip gets the ip address of the device.
