0/8 -2/8 were reserved. 3/8 went to GE. 4/8 went to BBN Planet which was eventually bought by Nortel ( I think) and I think it's Level3 owned today. 5/8 was reserved ,6/8 & 7/8 was DoD, 8/8 went BBN again, 9/8 to IBM, 10/8 went to us all, 11/8 to DoD, 12/8 to AT&T.All these allocations were a time before classless routing.Not counting the authority, BBN got the first /8 in 1992. I never found why BBN wasn't given 3/8. Anyone remember?
