Class A address Subnetting Help

[macdiesel1]

I feel I can pretty much subnet a Class B or Class C network address with no problems. When it comes to class A I get stumbled because the numbers get very large and I can't do the math quickly in my head.

How would you solve the following problem using the binary method and no shortcuts. I would really appreciate it. I can get the subnet mask no problem. How do i determine what the 303rd subnet would be easily??

Network: 14.0.0.0

Need 500 Subnetworks with as many hosts per subnet as possible
--------------------------------------------------------------------------------
Solve for -

Subnet Mask: ____________________________________

For the 303rd usable subnetwork, give the IP address for:

Wire (network) #:________________________

1st Usable:___________________________

Last Usable:_________________________

Todd...just noticed this...

"I get 255.255.255.128.0 for the subnet mask."

Your first post in this thread...lol

$1.61---I'll look tomorrow...

Yeah, Cluebird pointed that out to me later. That many subnets and binary math, if that's all I screwed up, I'm happy.
