Mergers of entities having an IP address range is a primary reason of entities having multiple address ranges. As IPv6 was developed a lot later than IPv4, it has not suffered from mergers so much yet.
Yes. You are completely correct. But, those entities usually have one v6 prefix each. And multiple v4 ones. Because they've required more addresses. Not everyone are Apple, "hp"[0] or MIT, where initial allocation still is mostly sufficient. (I believe MIT handed some back too) Instead they had to ask repeated times for smaller and smaller chunks of addresses. (Now they're buying them for prices that may well be motivating people to come up with crazy schemes of reusing reserved addresses.. ) In contrast, the v6 allocations are mostly sufficient. Even for sprawling businesses. In the end, if they merge with another company, each merger brings one (1) more net, not a flock of v4 /24's. Your reasoning is correct, but the size of the math matters more. -- Måns Nilsson primary/secondary/besserwisser/machina MN-1334-RIPE SA0XLR +46 705 989668 Content: 80% POLYESTER, 20% DACRONi ...
