i'm having trouble creating a IP Adressing Scheme, I have been given 15 sites each of these are connection via MPLS or leased line. For the first site I have determined I need 1700 nodes my tutor also said it requires 50 WAN links and 70 subnets (But I don't understand the reason for this)
I have got an IP address of 220.127.116.11 /21 and a mask of 255.255.248.0
Am I right in thinking that leaves me 21 bits left, making it a /21 network with a max of 2046 hosts?
I'm using a Class B network but am not quite sure if that is big enough, if not I would change it to Class A ?
The problem am having is how can I calculate the IP scheme and how many hosts I can have one each one?
Thanks for any advice.
