IP-HTTPS
Microsoft network tunneling protocol
From Wikipedia, the free encyclopedia
IP over HTTPS ("IP-HTTPS", "MS-IPHTTPS") is a Microsoft network tunneling protocol. The IP-HTTPS protocol transports IPv6 packets across non-IPv6 networks. It does a similar job as the earlier 6to4 or Teredo tunneling mechanisms.
Microsoft preference when deciding between transition protocols
Microsoft used to discourage IP-HTTPS use because it was slow.[1]
For Windows Server 2012, Microsoft changed the internal workings of the protocol, and IP-HTTPS is now the "preferred IPv6 transition technology" for their DirectAccess VPN technology.[2]
