@whitequark@social.treehouse.systems @tom_verbeure@mastodon.social @azonenberg@ioc.exchange @M0KHR@mastodon.radio MACs are 48 bit. So far there's still enough address space left for no collisions to be neccessary. And since bad things happen when you have an MAC address collision within a network segment, and the likelyhood of that only going up: I hope that 3com was an outlier. 3com bet on their doubly assigned cards to never meet in a shared broadcast domain. It happened within months.
