In computer networking, a firewall pinhole is a port that is not protected by a firewall to allow a particular application to gain access to a service on a host in the network protected by the firewall. [1] [2] Leaving ports open in firewall configurations exposes the protected system to potentially malicious abuse.
Officially, this mechanism was created for Microsoft Windows XP and onwards PCs to provide IPv6 connectivity to IPv4 clients by connecting to ipv6.microsoft.com and works in conjunction with IP Helper service and Teredo Tunneling Adapter Interface driver. The service also opens a UPNP port on the router for relaying.
Fast-paced online multi-player games may use a hole punching technique or require users to create a permanent firewall pinhole in order to reduce network latency. VPN applications such as Hamachi, ZeroTier, and Tailscale utilize hole punching to allow users to connect directly to subscribed devices behind firewalls.
Anything In Anything (AYIYA) is a computer networking protocol for managing IP tunneling protocols in use between separated Internet Protocol networks. It is most often used to provide IPv6 transit over an IPv4 network link when network address translation masquerades a private network with a single IP address that may change frequently because of DHCP provisioning by Internet service providers.
4in6 refers to tunneling of IPv4 in IPv6. [1] [2] It is an Internet interoperation mechanism allowing Internet Protocol version 4 (IPv4) to be used in an IPv6 only network. 4in6 uses tunneling to encapsulate IPv4 traffic over configured IPv6 tunnels as defined in RFC 2473.
IPv6 implements the Neighbor Discovery Protocol (NDP, ND) in the link layer, which relies on ICMPv6 and multicast transmission. [5]: 210 IPv6 hosts verify the uniqueness of their IPv6 addresses in a local area network (LAN) by sending a neighbor solicitation message asking for the link-layer address of the IP address. If any other host in the ...
There is a difference between a "relay router" and a "border router" (also known as a "6to4 border router"). A 6to4 border router is an IPv6 router supporting a 6to4 pseudo-interface. It is normally the border router between an IPv6 site and a wide-area IPv4 network, where the IPv6 site uses 2002:: / 16 co-related to the IPv4 address used later ...
IPv6-to-IPv6 Network Prefix Translation (NPTv6) is a specification for IPv6 to achieve address-independence at the network edge, similar to network address ...
