It depends on what is the benefit for any expense. For example, encryption cost is high, but there is a motivation that many people would accept (and create the pressure on the financial department to tolerate it).
For the case of half IPv6 address bits wastage, it was initially "OSI layer violation to put MAC inside IP address just because some IPX politicians have big enough weight" that was later replaces by "randomize IP address to make more difficult to guess it or scan". Number of people who would support this madness would be very small - OTTs have hundreds of ways to de-anonymize users. Hence, it is just a wastage of 2% of Internet for nothing.

So if you care about 2%, you'll use IPv6. On 6 November 2025 18:52:07 CET, nanog--- via NANOG <[email protected]> wrote: >So you use header compression on all your links, right?
