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.
This is what I don’t understand, maybe the 11.11.18.x block of addresses are more relevant to this..?
175,000,064 / 256 gives 683,594 different possible (xx.xx.xx).x configurations. I know next to nothing about internet networking, but what you said makes sense to me so I would need more info to make sense of the 175million number
I'm not a networking guy but I don't think any one address is has a denser set of sub-addresses. There are four octets, each have 256 possibilities. Though to be honest not sure if certain ones are invalid. For instance, can an ip start with a 0 octet? I think what I'm referring to is ipv4. Not familiar with ipv6 at all.
175 million IPs could brew up a he'll of a broadcast storm. Could cloudflare defend against it?
Isn't it 256 addresses 0 - 255 of 11.11.18.*?
The article in the pic mentioned 175mil

They could just block 11.*
Thats still only 16 million. There needs to be 10 other octets - I am thinking 1.* - 11.*
