Yes ... this is correct 172.16.0.0/12 to 172.31.0.0/12
I still use the "class" word ... :-) Regards, Greg DeGennaro Jr., CCNA Security Analyst, Infrastructure Engineering >Please have another look at your documentation. The so-called >"unregistered" IP-addresses are 10.0.0.0/8, 172.0.0.0/16 (i think, i >don't use these ones) and 192.168.0.0/16. Actually, I beleive it's 172.16.0.0/12. Way back in the good old days it was a block of 16 class-b networks, but of course no one uses the evil word 'class' anymore ;) --K
