Python ARP scanner

This code is an arp scanner, it scans all hosts on the network except phones.
Program print only ip and mac addresses of computers, not phones

Nobody knows why this happens? Thanks

import scapy.all as scapy

class scan:
    def Arp(self, ip):
        self.ip = ip
        print(ip)
        arp_r = scapy.ARP(pdst=ip)
        br = scapy.Ether(dst='ff:ff:ff:ff:ff:ff')
        request = br/arp_r
        answered, unanswered = scapy.srp(request, timeout=1)
        print('\tIP\t\t\t\t\tMAC')
        print('_' * 37)
        for i in answered:
            ip, mac = i[1].psrc, i[1].hwsrc
            print(ip, '\t\t' + mac)
            print('-' * 37)

arp = scan() # create an instance of the class
arp.Arp('192.168.0.1/24') # call the method

You need to add the interface your device is using.

answered, unanswered = srp(Ether(dst = "FF:FF:FF:FF:FF:FF") / ARP(pdst = ip), timeout = 1, iface = 'wlp1s0', inter = 0.1)

Have a look at https://stackoverflow.com/a/57017630/5459467 Some phones simply don't answer to ARP pings, mostly iPhones.

That's not necessarily explained anywhere, and could have multiple explanations such as: - security concerns - battery management

They will also tend to ignore gratuitous ARP. The only actions you can actually do is to answer faster than the router when they perform actual ARP requests, or simply sniff passively all ARP requests.
