Its partially there. C and D are still not in the global tables according to routeviews ie. 185.89.219.12 is still not being advertised to anyone. My peers to them in Toronto have routes from them, but not sure how far they are supposed to go inside their network. (past hop 2 is them)

% traceroute -q1 -I a.ns.facebook.com

traceroute to a.ns.facebook.com (129.134.30.12), 64 hops max, 48 byte packets 1 torix-core1-10G (67.43.129.248) 0.133 ms

Oh my gosh, their IPv6 address contains "face:b00c"...

Besides being fun and quirky, it is actually useful for their sysadmins as well as sysadmins at other orgs.

Well at least it will in 2036, when IPv6 goes mainstream.

How difficult is to get such a "vanity" address?

You just need to get a large enough block so that you can throw most of it away by adding your own vanity part to the prefix you are given. IPv6 really isn't scarce so you can actually do that.

The face:b00c part is in the Interface ID, so this did not even need a large block (Though I am sure they have one).
