Well, comparing the results of "proc" and "netstat" via
	print ("debug: %s:%i\t%s:%i" % (laddr, lport, raddr, rport) ))

shows these things :

1. both have few duplicate lines (2-3 for netstat, about 6 for proc)
2. proc expands the ipv6 addresses, eg.: 2a01:4f8:190:514a::2 into 2a01:04f8:0190:514a:0000:0000:0000:0002
3. the resolver netstat have significant lines more w/o any patterns why
4. proc is the only resolver which differs, lsof, netstat and ss have comparable results
5. the output of netstat is nearly identical to "na -n | wc -l"
