This zine also has a print version that you can print and fold and staple. The print version is linked here: http://jvns.ca/zines/#networking-ack.
I wrote this in large part because I love being able to print out zines about my favorite topics ("hey, want to know more about computer networking?! I wrote a small thing you can read about it!!") and give them to people who might not otherwise read about the subject.
I love your zines. I have a pack of them here waiting for distribution at our next meetup here in Brazil. Thanks a lot for the hard work, it is very inspiring!
I write them all on a 10 inch Samsung tablet (with an "S pen") in an app called Squid. Writing them on a tablet really helps a lot -- my first zine was on scanned paper, and it was fun (you can see it at http://jvns.ca/strace-zine-unfolded.pdf) but it was hard to edit and the results didn't look nearly as good.
If you use an ipad pro, there's an app called Goodnotes which is quite good for drawing things like this. They both give you vector images so you can scale them up to any resolution.
There's a mistake on page 4 in the structure diagram. It says the first block of a packet is 14 bytes == 84 bits. But 14 bytes is 112 bits, as is seen on the repeat of the diagram on page 15.
A MAC address is 48 bits, so 2 MAC addresses and a type can never fit into 84 bits.
