Yes, 64-bit math will be faster, that is math involving integers greater than 2^32. How often do we do that?
Well, IPv6 addresses are 128 bits. That's 2 words on a 64 bit CPU and 4 on a 32 bit.
Yes but both IPv4 and IPv6 have what amounts to segmented address spaces. Look at it this way (IPv4 example) If I have the 'Class C subnet' x.y.19.0..255 and Bob in the next township[1] has x.y.20.0..255 then when I'm auto-assigning addresses and get to x.y.19.225 and auto-increment do I end up with an address in a different subnet or no? Some things you don't do arithmetic on. [1] The joke is that James is - minus the city amalgamation that abolished all the village and townships - just a couple over from me. -- /"\ \ / ASCII Ribbon Campaign X Against HTML Mail / \ -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
