That /32 may have been too much for YOUR needs, but you are
not the only one whose needs are analysed. In particular, the
global community of network operators also has needs, and those
needs are better served by giving you a /32 even if, on the
surface of it, the allocation appears too big.
1. We can afford to give every operator a /32, not matter
2. By giving everyone a /32 and encouraging them to announce
a single prefix, we reduce the profile of a single network
operator to a single entry in the global routing table. There
are exceptions of course but that is by far the most common
3. If we gave smaller operators longer prefixes, many of them
would come back for additional, non-aggregatable allocations
as their business grew. By giving out the /32 to everyone, we
minimize the impact on the global routing table of many
extra non-aggregatable allocations.
P.S. You cannot understand IPv6 piecemeal or by comparing
IPv4 things to the IPv6 equivalent, because there often is
no equivalent in IPv6. Twisting the meaning of things in
IPv6 to conform to an IPv4 world view just leads to confusion.
Try to understand IPv6 as a holistic system of networking
that has a family resemblance to its ancestor, but also
incorporates new genetic material.
