Document Summary
Iana allocates ranges (blocks) of ip addresses to various organizations, leaving the organizations themselves to decide how those addresses are to be allocated to specific hosts. Many of these organizations will be sufficiently large that they may, in turn allocate smaller blocks of ip addresses to individual departments with their own it support teams. All ip addresses at queen"s are taken from the block of ip addresses that start with 130. 15. Thereafter, various subnets are allocated to specific departments. The first users of the internet at queen"s perhaps not surprisingly, were in the department of. Computing and information science (cisc), now called the school of computing. Thus, the first subnets at queen"s = 130. 15. 1, 130. 15. 2, etc. came under control of the school. Ipv4 allows for fewer than 4. 3 billion (roughly 256^4) unique addresses.
