RE: IP Subnetting Question

[McCallum, Robert]

As phil has said mate, it is in the question!   They have probably asked how many bits of subnetting are being used in which case the answer is perfectly correct.  You are giving the answer as the full mask = natural mask + subnet mask -----Original Message----- From: Robert Cabeca [mailto:[EMAIL PROTECTED]] Sent: 17 October 2000 18:00 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
