[MLB-WIRELESS] Waterproof Boxes & IP Allocation

[Jason Brice]

	What is an IP Block?  Is it a range of IP addresses that the
node can use?   Yes that's right.  What is the /28 part of the address?
The /28 denotes the length of the subnet mask in bits. It effectively
dictates how many IP addresses are in your subnet (network)
	 
	for example;
	 
	(each number in the subnet mask represents 8 bits) 
	 
	/24 = Subnet Mask 255.255.255.0 (256 IP addresses)
	/25 = Subnet Mask 255.255.255.128 (128 IP addresses)
	/26 = Subnet Mask 255.255.255.192 (64 IP addresses)
	/27 = Subnet Mask 255.255.255.224 (32 IP addresses)
	/28 = Subnet Mask 255.255.255.240 (16 IP addresses)
