如何在 ios iphone swift 中获取热点连接设备的 IP 地址和 MAC 地址？

Question

My requirement is like, I want IP and MAC address of devices which are connected to my iOS device's hotspot. How can I get a list of IP address of those devices? Does Apple allow to get hotspot related information through code.?

Answer 1

Unfortunately I don't know a way to get the actual client list (or ARP table for that matter).

But you could implement a scanner. Have you thought of that? Isn't the beautiful solution you're most probably looking for, but might be something?

Here would be a scanner library as reference: https://github.com/mavris/MMLanScan

You could also get your devices IP address and network mask, calculate the possible IP range yourself and implement an ARP query per candidate device using sysctl and gethostbyaddr as described in this post

EDIT sidenote: Did you have a really deep read of the NetworkExtension API from Apple? I don't know it well but since it allows numerous configurations that might be possible as well.
