Only your Network / Domain / Systems Administrator will be able to answer your question. I searched the internet for answers to the above queries, but I am unable to find clear answers. If i do ipconfig /all, why is only one Teredo present while four 6to4 are present ? To be enabled by default? Any specific reasons for it? Shows a 6to4 tunnel adapter (Tunnel adapter LAN connection 16) It seems that Teredo should alone enabled by default in Vista,īut my system does not show it to be enabled by default. Intra-site mechanism, while the 6to4 and TeredoĪre for inter-site tunnelling mechanisms. That is, to put in simple words, ISATAP is an IPv6 packets between dual-stack nodes on top

Local link, with mappings from each IPv4 address ISATAP treats the IPv4 network as a virtual IPv6 That are located behind IPv6-unaware NAT devices That is, It is to grant IPv6 connectivity to nodes

Uses UDP encapsulation across multiple NATs. Teredo is an automatic tunneling technique that It is typically used when an end-user wants toĬonnect to the IPv6 Internet using their existing Tunneling that uses protocol 41 for encapsulation. Tunneling so that the tunnel endpoints are determinedĪutomatically by the routing infrastructure.Ħto4 is recommended by RFC3056 for automatic I understand that the above are for automatic
