ISATAP (Intra-Site Automatic Tunnel Addressing Protocol)
Purpose of ISATAP
ISATAP is a transition mechanism used within an organization’s network (intra-site) to facilitate communication between IPv6 and IPv4 hosts.
How ISATAP Works?
ISATAP creates IPv6-in-IPv4 tunnels within an organization’s network. IPv6 hosts use ISATAP routers to encapsulate IPv6 traffic in IPv4 packets, allowing communication with both IPv6 and IPv4 devices.
Advantage of ISATAP
ISATAP is suited for organizations transitioning to IPv6 within their internal networks. It helps maintain IPv4 compatibility while gradually adopting IPv6.
Disadvantage of ISATAP
ISATAP is not suitable for connecting IPv6 networks over the global Internet, as it is intended for internal use. It also requires proper configuration and management within the organization.
IPv6 Transition Mechanisms: 6to4, Teredo, ISATAP
IPv4 transition mechanisms are designed to keep IPv4 and IPv6 networks constant during the transition from IPv4 to IPv6. These mechanisms help devices and networks communicate with each other, even when using different versions of IP. The three most common IPv6 switching protocols are 6to4, Teredo, and ISATAP.
