I agree in general and I cheer for IPv6 becoming more widespread

The only cases when I type IPv4 addresses from memory is when I don't have working DNS - either when debugging DNS, or when manually configuring the first interface of a host, on a network with no DHCP.
Unfortunately, these are the cases where I can't rely on DNS to remember IPv6 for me.
It's not a deal-breaker but it does add some friction.
