I guess what im trying to figure out is WHY /19 would equal 8192 IP's?
/19=8192, this is what doesnt make sense.. i guess what im trying to say is i dont understand the formula or equation they are using that gives them justification to describe 8192 IP's as a block of /19.
Thats what im trying to figure out.. see what i mean?

An IP number consists of 32 bits. "/19" means that 19 bits out of those 32 are used to designate the network (alternatively you can say that 19 bits are used for the netmask). That leaves 32-19 = 13 bits to describe hosts on that particular network. 13 bits is enough to describe 2^13 = 8192 different hosts.
