I started learnign about the web byl earning about SEO and Im not quite sure if most SEOs really know what an IP address is (neither myself and im really confused, now!).
Is the 3rd octet the "c class" of an IP address (thus also called "c block")

or

is an IP address a "c class" IP address if the first octet is assigned a numerical value from 192 to 223?

or do both possibilites exist depending on whether its the internet or a local network or something? Im interested in what it is on the web (obviously).

thx!
