Telling people to use ULA subnet fddd:: with dhcpv6 is my way.

fddd::7 is easier to type than 10.0.0.7

"ten oh oh 7" (how I'd say it or remember it) still seems simpler than "eff dee dee dee colon colon 7". While with ipv4 the dots can be assumed for pauses, v6 doesn't put colons as often, also I could easily see myself forgetting the amount of "d"s. I don't wanna seem too anti-v6, though, I am in favor of everyone adopting the more modern thing.

edit: Well, you said easier to type. I guess I probably agree with that.

There is also the fact that an IPv6 IP has a maximum and minimum number of characters and separators, but not a set one, so the length of any given address is variable.

Instead of being able to run a groove in my head mentally, and read with any sort of rhythm, I have to read them like binary bytes. Every address feels like a foreign phone number where your normal rhythm doesn't fit, but it never gets better.

Perhaps, IMO, the greatest and only sin of IPv6. That and using fucking colons.

Dots weren't an option, because then the syntax would overlap with DNS hostnames. "2001.db8.c.d.e.f.g.ca" is a valid host under the .ca TLD.

one of those addresses requires two hands and hitting the shift key, the other is easily done one-handed.
