In the new world, the all zero's and the all one's subnets may be used. On Cisco equipment, the all one's subnet has been a default for quite a while. The all zero's was invoked with the command ip subnet-zero I believe that with IOS images greater than 12.1, that all zero's is enabled by default. > > Thx, > Sam Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=65602&t=65597 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
RE: Simple IP address question [7:65597]
No, you get eight subnets. Subnet zero and the all-ones subnet are legal under current standards.

The network is 199.66.15.224/27... your basing your info on classfull teaching in the ccna. the address listed in your example works fine..

RE: Simple IP address question [7:65597]
You also get the subnet that the address is on. In this case, the subnet is 199.66.15.225 - 199.66.15.254 with a broadcast of 199.66.15.255. Hope this helps.

RE: Simple IP address question [7:65597]
You should get 8 subnets rather than 6. The two additions: 1-30 & 225-254.
