> IPv6 reintroduces equity to the internet that facebook benefited from in it's inception

Except for the fact nobody can type, much less remember any IPv6 address.

and how many people remember public ipv4 addresses besides a couple of easy to remember ipv4 addresses like 1.1.1.1 for instance?

rfc1918 address space is easily remembered because people use mostly 192.168.xx.xx. but ipv6 has the same idea and when writing it shorthand isnt significantly larger.

When I worked at a company with about 5-6 servers and a couple fixed remote workstations, all the programmers knew all the IP addresses by heart, if there were names for anything but the www host I didn’t know them.

Obviously doesn’t scale, but I would assume this was normal back when you only interacted with say <10 servers.

That’s a false issue nowadays. Basically any cheap router supports Avahi/Zeroconf/Bonjour … and allows you to reach any other machine of the network directly by its host name instead of its IP. There is not any reason to learn the IP address of your first MySQL server when you can reach it through « mysql-1 » or « mysql-1.local ».

You basically just need a router and an OS from the last two decades and your machines to have a defined host name (which your OS installer takes care of).

I don't think that's true. I've never seen a router that lists hostnames that I can actually ping. Sometimes they do but 50% is always empty. It's a very client dependent solution.

I regularly run into instances where local hostname resolution is unreliable.

To improve reliability, I setup a local DNS server to hand out a domain name with the IP address. Even then, whether a client requires a hostname or FQDN to resolve a local address - that can vary over time.

They are easy enough to remember for a few seconds if you need to configure it somewhere. I always ping 8.8.8.8 to verify my internet connectivity. I don't think people should underestimate how much IP addresses are entered manually on a daily basis.

This is true, which is why I expect mDNS and DNS to become standard even for local addresses.

I'm looking forward to using `router.local` over `192.168.1.254`.
