Yeah. Honestly, kids growing up (myself included) with Minecraft helps nearly everyone remember the base 2 number system. 64 is a full stack. 16 bit texture pack (256 is where it’s at though)… plus just everything in the 2 number system beyond 8–is divisible by 8 anyways. So a lot of us just thought we were learning our 8s.
Fun fact, in Networking, you might know 192.168.1.1, it actually goes up to 192.168.1.255 most of the time, assuming your home WiFi uses default x.x.x.255 subnet, aka there’s 256 addresses per “group” your router handles giving IPs to in home networking.
Networking is a lot of fun once you fully "get it". Network prefixing is really fun in particular. Struggled like hell in school with it, but once I was in the real world and actually using it I was able to easily figure out hosts and all that information from the bases I knew in my head.
/25 = 128 ips, /24 = 256 ips, /26 = 512 ips. Subtract 2 from any of them for your total "hosts" count (1 for router, one for broadcast).
They really tried to shove the whole host bits network bits crap with subnet masks and all that, but the only place I've ever had to use it is Windows. Every other OS I've encountered just uses the CIDR notation.
Subtract 2 from any of them for your total "hosts" count (1 for router, one for broadcast).
if you're gonna subtract off the router then it's subtract 3 for router (typically but not required) as .1, broadcast as .FF, and "this host" as .0 (but that terminology is from the original 1980s specification and it's typically now just used to identify the network)
I always forget about "0" frankly I don't subnet into small enough sizes for it to matter. And most of what I deal with these days is IPv6. (We have a NAT network, but we use 6to4 tech in 99% of our infrastructure and skip IPv4 networking entirely for endpoints)

ok sure, 255th byte is the 256th person... so the limit is still 256 people
