You do have a point there. WindowsXP(netstat) [2001:db8::1]:80 FreeBSD7.1(netstat) 2001:db8::1.80 FreeBSD7.1(ipfw) [2001:db8::1]:80 Linux CentOS4(netstat) 2001:db8::1:80 linux+apache [2001:db8::1]:80 square brackets may be the more popular but this is debatable. For example Unbound's log gives "2001:db8::1 port 53" and that's not so bad. Are there others who think this should be covered in the draft? Any ideas?
