How many IPs in a /29? Need a quick clarification! or Can someone explain how many IPs in a /29 actua

Wait, does this include the gateway IP? Or is that separate?

Like, if I have a /29, is the gateway one of the 6 usable IPs? Or do I need to reserve another one?

Asking because I’ve seen both ways and now I’m second-guessing everything lol.
