> Unlikely What is your basis for this opinion? Network operators are already talking about it. > Too late. IPv4 are set to hit 1024K (2^20) in January 2024 at current trends Allow me to expand that number for you: 1,048,576 One million. A reasonable upper bound for max announced v4 prefixes is somewhere around two million. You can handle that in a few GB of RAM. IPv6 could see 100x or 1000x that number based on how we are handling allocations, at which point prefix trimming will happen.
