in CCNA & CCENT
I did some research, not a whole lot, primarly because I wanted it approved by this community.
The 1st and Last Subnets are dropped according to Cisco standards ?
When taking test if Im asked to assign e0 to 1st useable IP of first subnet do I assume the first subnet is void and move to the next ?
IE: First IP 198.25.36.0/27?
198.25.36.33 ?
Thanks for the Help

Traditionally, zero-subnet and all-ones-subnet were reserved. However, Cisco routers can be configured to override that using the command "ip subnet-zero". This command is enabled by default since IOS version 12.0. It means that you can use the two subnets by default for IOS v12.0 or above.KPLAB

But, for the purposes of the CCNA exam, the first and last subnet are not available unless the questions states otherwise= Marcus Drakonblayde
