Former ARRIS International MAC address blocks
The IEEE registry once carried 10 blocks registered to ARRIS International. All 10 blocks are now registered to Commscope. Commscope took over all of them.
Complete as of the current IEEE registry deploy. Dates are when each registration was first observed in public data, not legal assignment dates.
