teredo tunneling

The IPv6 tunnel is a IPV6 message encapsulated in the IPV4 message, allowing IPV6 packets to communicate through the IPV4 network. For equipment adopting tunnel technology, the source and destination address of the IPV6 datagram is encapsulated into the IPV4,IPV4 message at the entrance of the tunnel, respectively, the IPV4 address of the tunnel entrance and the tunnel exit, and the IPV6 message is forwarded to the destination node at the exit of the tunnel. Tunnel technology only requires modif

existing IPv4 facilities to serve IPv6 hosts, so that scattered IPv6 "islands" can communicate with each other across IPv4 networks. When an IPv6 packet passes through an IPv4 network, no matter which tunnel mechanism requires "packet-Unpacking", that is, the tunnel endpoint at the sending end encapsulates the IPv6 packet in an IPv4 packet, the IPv6 packet is regarded as IPv4 load data, and the protocol field of the IPv4 packet header is set to 41 to indicate that the load of the IPv4 packet is

IPv6 transition solutions include dual-stack, 6to4, Teredo, and Tunnel ). Among them, 6to4 and dual-stack require ISP support. Teredo actually packs the IPv6 protocol into IPv4 UDP for sending. This method is not recommended in Microsoft technical documents, and finally give up. Therefore, IPv6 Tunnel is the most practical situation for the majority of Internet users. Note: The following solution is applica

namespace. For example, Contoso uses contoso.com on the Internet to use corp.contoso.com on the Intranet. Because all intranet resources use the corp.contoso.com DNS suffix, corp.contoso.com's NRPT rule routes all DNS name queries for intranet resources to the intranet DNS server 。 DNS name queries with names with the contoso.com suffix do not match the corp.contoso.com Intranet namespace rules in NRPT, so these queries are sent to the Internet DNS server.For non-split DNS deployments, no addit

In earlier versions such as XP and 2003, IPv6 addresses cannot be manually configured in the "Network Connection" attribute configuration. They can only be configured using netsh. The configuration method is as follows: First, install IPv6 Step 2: view the currently used local connection information: For example, if my name is "local connection 3", execute the following commands in sequence: C: \ Documents ents and Settings \ Administrator> netshNetsh> interface IPv6Netsh interface IPv6> sho
