Feature request for 128bit for ipv6 usage.

[ouvaa]

@lemire i would like to use 128bit for ipv6, thought of having 2 roaring bitmaps of 64bit each and splitting the ipv6 into 2 segments but i realised i have to call the roaring bitmap from 2 memory location twice.

1. possible to make a 128bit version?
2. do u have suggestions to make this faster or better? is it advisable to use ipv6 detection for "flagging" it as a banned ip or similar?

specifically asked u coz i know u are expert in extreme optimization and thanks for all the write ups you have done etc.

There is no plan to support 128-bit bitmaps. It is unclear whether it would be a good idea.

@lemire is this the best i can do currently? any alternatives worth exploring?

Maybe you could store these values in a BSI. The interface is 64 bit but you could either split the values into 64 bit words. Failing that it would be easier to modify the BSI sub-library to add support for BigDecimals. El mié, 17 de abr de 2024, 11:47 a. m., ouvaa ***@***.***> escribió:
