The Microsoft ISATAP device Inter Site Automatic Tunneling Address Protocol is used to help enterprises transition to IPv6 infrastructure. What is tunnel adapter ISATAP?Īn ISATAP adapter is a piece of software designed to help organizations transition from the older 32-bit Internet Protocol address infrastructure to the newer 128-bit IP system. To accomplish this, NAT64 translates incoming IPv6 packets into IPv4 and vice versa. A public IPv4 address is shared among several IPv6-only clients. NAT64 is a related technology that allows IPv6-only clients to contact IPv4 servers using Unicast UDP, TCP, or ICMP. The format of this address provides some key information: It is a valid IPv6 address that can be used for IPv6 communication. It does this by taking an IPv6 frame and applying headers to the frame with IPv4 network information. ISATAP is an interface that hosts can use to pass IPv6 traffic over IPv4 networks. What is Isatap and when should it be used? ISATAP works by mapping an IPv4 address into the IPv6 address and requires an ISATAP gateway on the IPv6 Internet and the IPv4 intranet. ISATAP is Short for Intra-Site Automatic Tunnel Addressing Protocol, ISATAP is a method of transmitting IPv6 packets on an IPv4 network that is most recently defined in RFC 5214.

This allows isolated IPv6 end systems and devices to communicate without the need to upgrade the IPv4 infrastructure that exists between them. IPv6 over IPv4 tunnels are point-to-point tunnels made by encapsulating IPv6 packets within IPv4 headers to carry them over IPv4 routing infrastructures. 6to4 a mechanism where a router with a public IPv4 address can be an IPv6 gateway or a provider for a whole sets of LANs. What is the difference between ISATAP and 6-to-4 tunneling? ISATAP transmits IPv6 packets between nodes on top of an IPv4 network. What is the difference between ISATAP and 6to4 tunneling? IPv6 Tunnels are stateless and have no knowledge of the configuration or even existence of the remote tunnel endpoint. It is used to form a virtual point-to-point link between two IPv6 nodes. IPv6 Tunneling is a mechanism for encapsulating IPv4 and IPv6 packets inside IPv6 packets.
