The .onion Special-Use Domain Name
The Internet Engineering Task Force has approved a Draft RFC for "The .onion Special-Use Domain Name"; also, today, the Internet Assigned Numbers Authority has added ".onion" to the list of Special-Use Domain Names.
Jointly, these actions enable ".onion" as special-use, top-level domain name for which SSL certificates may be issued in accordance with the Certificate-Authority & Browser Forum "Ballot 144" - which was passed in February this year.
Together, this assures the validity and future availability of SSL certificates in order to assert and protect the ownership of Onion sites throughout the whole of the Tor network - including https://www.facebookcorewwwi.onion/ and https://m.facebookcorewwwi.onion/
