With IPv4 you need to remember ... one number per machine. The one at the end, since it's usually a /24 and everything has the same prefix.
I'm sure it's trivial to remember mac addresses from different vendors with no connection to each other too :)

Hostnames are another layer. Your apple tv example may advertise itself on its own. My toys don't all do that.
- 9dev 6mo agoThat’s kind of my point, though. There is no reason at all to remember IP addresses.
- XorNot 6mo agoI don't care to remember them, but I do want them to be consistent so there's no dependency in DNS. My home network isn't the Internet and isn't large: DNS is a much more complicated system to keep running then just fixed IP addresses in that circumstance. Above a certain scale, that flips but not at the home level.
- 9dev 6mo agoAt the home level, you have a home router that can do mDNS out of the box. All devices are reachable by their hostname.
- XorNot 6mo agoA router which can be switched off sometimes, or break and delay replacement. I don't want all my IoT devices going down because they can't resolve hostnames - that's why I set fixed IP addresses for them. It means how they communicate with each other and my network is well-defined, and works provided they have Layer 2 (easy to keep up - it works provided any 1 AP is online, whereas my internet or the router providing it can vanish).
