> Router management pages

For home use, many current generation router/AP boxes are powerful enough to run a local DNS server (in addition to DHCP) and often hardcode a DNS entry for configuration, eg http://router

> internal network stuff in places small enough

The .local domain (ie http://hostname.local) has been a functional out of the box for many years now on osx/linux and NetBIOS have worked on Windows since forever.

Router management is something very common - and you start to learn all the OUIs very quickly, and fe80::0213:50FF:FE12:3456 starts to get into your finger DNA. Eventually you start to learn all your devices by the last 24 bits of their MAC address, and that's all you need to remembers - the first part (fe80::0213:50FF:FE) is natural.

In some ways, this is a big advantage of IPv6 over IPv4. You don't need those craptastic "Client Software" apps to configure the IP address (I'm looking at you Netgear), because every IPv6 device comes with it's only link-local IPv6 address, ready to go.
