/28 = 255.255.255.240   You are correct!!!   the /28 just means a 28 bit mask...  that is .240   :--) -----Original Message----- From: Robert Cabeca [mailto:[EMAIL PROTECTED]] Sent: Tuesday, October 17, 2000 10:00 AM To: cisco group study Subject: IP Subnetting Question I am not understanding the concept of using an IP address followed by /n. Example 10.20.193.20 /28. The way I am looking at it I get a Subnet mask of 255.255.255.240. But I am being told that it is really a mask of 255.255.240.0, however I am not being given an explanation. I thought that 255.255.240.0 has a /20. but it is a /12 instead? Any enlightenment would be appreciated.   peace Rob
