This was a huge hassle to figure out, so I wrote up a little guide in hopes that others would find it helpful:

How to convince macOS to do IPv6 DNS lookups when your only IPv6 address is via a VPN or tunnel of some sort

The Problem

macOS's domain name resolver will only return IPv6 addresses (from AAAA records) when it thinks that you have a valid routable IPv6 address. For physical interfaces like Ethernet or Wi-Fi it's enough to set or be assigned an IPv6 address, but for tunnels (such as those using utun interfaces) there are some extra annoying steps that need to be taken to convince the system that yes, you indeed have an IPv6 address, and yes, you'd like to get IPv6 addresses back for DNS lookups.

I use wg-quick to establish a WireGuard tunnel between my laptop and a Linode virtual server. WireGuard uses a utun user-space tunnel device to make the connection. Here's how that device gets configured:

	#!/usr/bin/env python
	''' Run from "electrum/lib" directory.
	ThomaxV started a discussion on https://bitcointalk.org/index.php?topic=274182.msg2939599#msg2939599
	about changing the HD derivation logic in electrum 2. The below post:
	http://bitcoin.stackexchange.com/questions/37013/how-to-import-a-hd-wallet-from-an-extended-private-key
	confirms that the format is actually m/c/i (and not m/44'/0'/a'/c/i)
	so I have altered https://gist.github.com/romanz/4b32782bfc0ff4984713 accordingly:
	tested to work with keys/addresses exported from electrum 2.7.0
	note Electrum has a "gap limit" of 20, so loop @ level "c" to get the next 20 addresses

	KDBX files, the keepass database files, are layout as follows:

	1) Bytes 0-3: Primary identifier, common across all kdbx versions:
	private static $sigByte1=[0x03,0xD9,0xA2,0x9A];

	2) Bytes 4-7: Secondary identifier. Byte 4 can be used to identify the file version (0x67 is latest, 0x66 is the KeePass 2 pre-release format and 0x55 is KeePass 1)
