What does the slash mean in the article? Where it says “... in 2018 GE sells 3.0.0.0/8” what does the “/8” mean? I guess it indicates the range of addresses?

- SheepSlapper 6y agoYou're right that it indicates a range of addresses, the number after the slash is the number of starting bits that the addresses all share.

- justusthane 6y ago/8 is the same as a 255.0.0.0 subnet mask. Also known as a class A subnet. In other words, literally any IP address that starts with “3.” In other other words, 16,777,216 IP addresses. In other other other words, about half a percent of the total number of public IPv4 addresses. Crazy.
