Not as much, you could learn the basics on ipv4 in two to three 4 hour classes of study - assuming you know how to convert between binary octal and decimal.

  The same is true of IPv6? There is really nothing deeply magical there that takes forever to understand. Maybe be a bit more concrete about what's so much more complicated about IPv6 than IPv4..

    What I am seeing here mostly is the biggest problem is that you can't hold an IPv6 address in your head. Ever. I can look at an v4 address then 15 seconds later look at another address and know they are different. That's not possible with v6. So I think people are conflating "difficult to wield" as "more complicated".

      If you only use autoconfiguration perhaps, but for manually assigned addresses it's really not too bad since one can structure them in a logical way (which would be extremely expensive to do in the IPv4 case). If you are a company you can get your own IPv6 space and can structure things hierarchically: <company prefix>:<site>:<vlan>::<hostnumber>. And in fact I can remember more IPv6 addresses for hosts than IPv4 addresses for the same hosts right now.. so there is that.

      And yet I have fe80:: in my head and 2001:db8:: in my head (as well as my own /32). I don’t have the documentation prefix (if one even exists) for IPv4 in my head. It’s harder, but “can’t... ever” and “not possible” are not true for everyone.
