It’s not how much they took, it’s how little it took.

The US has the cheapest representation their money can buy.

I’ve been calling all fossil fuels ‘artisanal energy’. It will eventually become as practical as other handmade, small batch products.

Configuring multiple v4 addresses on an interface is a kludge, typically only used on hosts which apply inter-network routing logic. It’s an explicit, primary function of the standard v6 specifications.

With v4, you would use either RFC1918 and NAT, or plumb a public address to the host.

With v6 you should use a ULA and an address with a public prefix, and selectively open ports/services to on appropriate address.

An example is the file sharing and administration daemons on my NAS are only bound to its ULA. I don’t need to worry whether it will accidentally be exposed publicly through fat fingering my firewall config, because it will never route beyond my gateway.

I use ULA prefixes to ensure the management interfaces of my devices don’t leak via public routes.

It’s one of the unique parts of the standard IPv6 stack not back ported to IPv4, that an interface on any host can be configured with multiple addresses. It permits functional isolation with the default routing logic.

IPv6 is far from perfect, but the majority of the arguments I’ve seen against deploying it are a mixture of laziness, wilful ignorance, and terminal incuriosity.
