Yeah, I think the article was incorrect. If the first three octets are set, there are only 256 remaining for the last octet. The only guess I can make at the discrepancy is that maybe someone was calculating the number of addresses behind 11.*.*.*, which would be 256*256*256 = 16,777,216. The numbers still don't match, but closer.
The article in the pic mentioned 175mil
