  1. OMG I cannot believe how easy IPV6 is. Granted this is my first time passing through these lessons and if I didn’t recover or think about what I just learned it could easily be forgotten but you really have me looking at it differently.

    I like to count backwards from right to left when doing my summaries and one thing about hex that makes it easy is that its in blocks of 4 “0000” so its always “8 4 2 1” those are easy numbers to work with and that part is just simple math but more pattern and grouping really and I love patterns and groupings its how my m

    then, if there is no constraint in the exibit asking to exclude all before 2001:db8:1234:ab7f:ffff:ffff:ffff:ffff
    and all after 2001:0db8:1234:ac00:0000:0000:0000:0000, I think an “industrial” summarization may be 2001:DB8:1234:AB00::/56 (pool fr

    Then, if there is no constraint in the exibit asking to exclude everything before 2001:db8:1234:ab7f:ffff:ffff:ffff:ffff and everything after 2001:0db8:1234:ac00:0000:0000:0000:0000 I thinks that an “industrial” summary can be 2001:DB8:1234:AB00
