An engineer and I were discussing that if our network has more network than actual needed would cause wasting bandwidth. For examples, if our company has only 200 devices are actually on a network, but our network is 10.0.0.0/8 then we are wasting bandwidth for those that we don't use. I don't think its true because there are only 200 devices on network then only 200 devices are using network bandwidth even you have more host in your network subnet than actual devices. I'm not sure if it's true. Anyone can explain to me?
Thanks in advance.
