ISATAP (Intra-Site Automatic Tunnel Addressing Protocol) is an IPv6 transition mechanism meant to transmit
IPv6 packets between dual-stack nodes on top of an IPv4 network. ISATAP specifies an IPv6-IPv4 compatibility
address format as well as a means for site border router discovery. ISATAP also specifies the operation of IPv6 over
a specific link layer - that being IPv4 used as a link layer for IPv6.
