dns tunneling

The tunnel technology is used to connect the two networks that are currently used by both protocols, that is, the IPv6 network and IPv4 network, to ensure compatibility. Now let's mainly analyze this technology. Tunneling Technology In the early stages of IPv6 development, there must be many local pure IPv6 networks, which are isolated by IPv4 backbone networks. In order to connect these isolated IPv6 islands, we will adopt the tunnel technology to so

Knowledge Point Analysis: Teredo is an address assignment and inter-host automatic tunneling technology that helps users establish IPV6 unicast connections when Ipv6/ipv4 hosts are located behind one or more IPv4 NAT. IPV6 packets are sent as UDP messages based on IPV4.The exclamation point device "Teredo Tunneling Pseudo-Interface" appears in Device Manager because the operating system does not correctly

Transferred from someone else's article: 78385506 Clients typically use Web proxy servers to access Web servers on their behalf. For example, many companies place an agent on the corporate network and on the security boundary of the public Internet. A proxy is the only device on the firewall router that allows HTTP traffic to be exchanged, and it may perform virus detection or other content control work. But as soon as the client begins to encrypt the data sent to the server with th
