How Does This Work, Anyway? Subnets are defined by CIDR notation, which is just a concise way of representing a range of IP addresses. For example, 192.168.1.0/24 represents the range from 192.168.1.0 to 192.168.1.255. The number following the slash indicates how many bits are used for the address (in this case, the first 24 bits, which make up the first 3 bytes) and the rest are given to be allocated to devices (in this case, the final 8 bits, making up the last number in the address)....

This type of 5G is superfast but has very short ranges....
