+<code>
+During the Joint Techs meeting at Fermilab Ron Broersma of Defense Research and Engineering Network
+(DREN) included a scorecard in his presentation that tried to quantify how well major organisations
+were embracing IPv6. I thought that this was such a fine idea that I’ve decided to replicate it here.

+IPv6 Testing Tools

+====== Disabling RFC 4941 IPv6 Privacy Extensions in Windows ======
+From: https://andatche.com/articles/2012/02/disabling-rfc4941-ipv6-privacy-extensions-in-windows/
+<code>
+RFC 4941 defines a series of Privacy Extensions for Stateless Address Autoconfiguration
+in IPv6
+By default, Windows Vista, Windows 7 and Windows Server 2008 generate random interface IDs
+for non-temporary autoconfigured IPv6 addresses, including public and link-local addresses,
+rather than using EUI-64 derived interface IDs.1 While these are permanent, so don’t change,
+this leads to potential confusion when a host’s expected EUI-64 derived address is unreachable!
+Thankfully it’s trivial to disable this behaviour, fire up cmd.exe and issue the following.
+netsh interface ipv6 set global randomizeidentifiers=disabled store=active
+netsh interface ipv6 set global randomizeidentifiers=disabled store=persistent
+In addition to this, the RFC states that the use of temporary addresses should be disabled
+by default.
+The use of temporary addresses may cause unexpected difficulties with some applications.
+[snip] Consequently, the use of temporary addresses SHOULD be disabled by default in order
+to minimize potential disruptions. Individual applications, which have specific knowledge
+about the normal duration of connections, MAY override this as appropriate.
+Windows Vista and Windows 7 ignore the advice of the RFC and also configure temporary global
+or unique local addresses as per RFC 4941 (EDIT: OS X also does this since 10.7, so do many
+Linux distros). This behaviour is disabled by default on Windows Server 2008.
+To disable privacy extensions entirely, fire up cmd.exe and issue the following.
+netsh interface ipv6 set privacy state=disabled store=active
+netsh interface ipv6 set privacy state=disabled store=persistent
+The changes will take immediate effect without needing to reboot, they’ll also persist
+after a reboot.

+====== Multicast Address Space Registry ======
+From: https://www.iana.org/assignments/ipv6-multicast-addresses/ipv6-multicast-addresses.xhtml
+<code>
+IPv6 multicast addresses are distinguished from unicast addresses by the
+value of the high-order octet of the addresses: a value of 0xFF (binary
+11111111) identifies an address as a multicast address; any other value
+identifies an address as a unicast address.

+====== Best Current Operational Practice for Operators: IPv6 prefix assignment for end-users ======
+From: https://www.ripe.net/publications/docs/ripe-690
+<code>
+Best Current Operational Practice for Operators: IPv6 prefix assignment for end-users -
+persistent vs non-persistent, and what size to choose
+Non-persistent prefixes are considered harmful in IPv6 as you can't avoid issues that may be caused by
+simple end-user power outages, so assigning persistent prefixes is a safer and simpler approach.
+Furthermore, this avoids the need for expensive logging, increases your chances to offer new business
+to customers, and decreases your customer churn.
