Content
The current code and proposed changes use 'netstat -ia' to find the node however if netstat needs to perform a reverse DNS query to resolve some interfaces this makes using uuid1 really slow especially when reverse DNS queries aren't set up correctly or timeout. mac = _find_mac_netstat('netstat', '-ia', b'Address', lambda i: i) Would it be possible to change the netstat call to add 'n' to the nestat options, i.e. _find_mac_netstat('netstat', '-ian', ...) to prevent netstat from attempting to resolve addresses?
