An octet isn't limited just to IP address notation.. it can be any group of 8-bits. It's also commonly used to describe segments of a packet or "fields" in a header, but can also apply to data. Octet is usually the equivalent of a byte but not necessarily. With the advent of minicompters in the 60s, a word was 16 bits and a byte was half a word. When word lengths grew to 32 and 64 bits, the meaning of byte became ambiguous... sometimes a "byte" meant 16 or even 32 bits. So "octet" was coined to eliminate confusion.
