> maybe I broke DNS or something

I break my DNS very often, or at least, often enough that it'd become nuisance that I can't instantly recall IP address of every machine in any of my 5 VLANs, AND type it in manually within 3 seconds.

With IPv6, I'd have to drop whatever I'm doing and fix my DNS first.

If you use SLAAC and don't use mDNS, I suppose, maybe? But if you break DNS often enough that you need to remember IP addresses, you can just do DHCPv6 if you want IPv4-like address allocation.

It'll be even easier because you can use numbers greater than 254 for your local devices, or l33t-style hex addresses, without setting up routed subnets when you exceed your /24 like on IPv4.
