It's 2018 after all :) Another person wrote to inform me of Python's ipaddress library, in the standard library collection, making it much easier for me to expand to IPV6. I should be able to do it as soon as I understand IPV6. > > Also, sthen, since it is 2018 .. you shouldn't be using eui64 > addressing anymore ;-) I'm confused. Was I using eui addressing in the IPV4 version? If I shouldn't use eui, what *should* I use instead? My understanding from 10 minutes of reading is that eui is a way of auto-setting IP addresses within the subnet, based on Mac addresses, which are presumed unique within the subnet.
