Can I get a ELI5 on why IPv6 is bad or not very good?
ipv4 is a 32-bit number, which means the total number of possible addresses are 2^32^ = 4 294 967 296, which is waaaaay less than the amount of computers we have today. ipv6 is a 128-bit number, so the total is 2^128^ = 340 282 366 920 938 463 463 374 607 431 768 211 456, which is more than all the grains of sand on earth.
the only thing i've heard people don't like about ipv6 is that the addresses are longer and have letters in them.
Minor correction: IPv6 uses 128bit addresses.
oops, yeah.
yeah the frames are different but that doesn't matter to 99.9% of people.
Thank you for the reply. That clears things up for me.
