What is meant by IPv4 number block?

IPv4 number block again, is a group of contiguous numbers with a categorized starting number at a location that is defined in the routing policies asan “bit boundary”. The size of a number block can be as small as a single number, which in CIDR notation, would be referred as a /32 block, or as large as the total potential number range, which else in CIDR notation would be shown as /0. Actually, the largest number blocks allocated to single entities are known as /8’s and contain arround 16,777,216 individual contiguous numbers.
