hey, i know this vid kept it to ipv4, but i’ve got a few questions maybe you could answer real quick…

  • aside from the obvious (bigger numbers, different presentation format) is there really that much difference between ipv4 and ipv6? cidrs, masks, etc. all work the same way, don’t they?

  • do these all represent the same address? do they all route/map to the same address? can you expound on the differences/use cases for each?

    192.168.10.1
::192.168.10.1
::c0a8:a01
::ffff:c0a8:a01

  • how official/common/understood is “not.network.ip.addr/cidr”? e.g., is 192.168.10.42/24 universally understood to mean “192.168.10.42 on the 192.168.10.0/24 network”?

i think i know the asnwers to most of these, but i have been overthinking things and confusing myself.
thanks!

indeed.
