IP-HTTPS

{{Short description|Microsoft network tunneling protocol}}

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.

| quote = The problem with IP-HTTPS is that it should be considered, and is instantiated as, a protocol of last resort. [...] the primary reason being that it’s the lowest performing of the IPv6 transition technology protocols.

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.
