http://www.cisco.com/warp/public/701/3.html   This is a pretty good link for brushing up on IP addressing and subnetting.  Lot of examples for the beginner.   Vijay Ramcharan CCNP, CCDP, MCSE -----Original Message----- From: Marshal Schoener [mailto:[EMAIL PROTECTED]] Sent: Tuesday, October 17, 2000 1:29 PM To: 'Robert Cabeca'; cisco group study Subject: RE: IP Subnetting Question /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
