IP Blocks:
- Usually a Public Address which need to be accessed is been purchased.
- IP addresses are assigned to networks in different sized ‘blocks'.
- Size of the ‘block' assigned is written after an oblique (/), which shows the number of IP addresses contained in that block.
- For example, assigned a “/16”, they receive around 64,000 IPv4 addresses.
- Lower the number after the oblique, the more addresses contained in that “block”.
