  2. Default route - Wikipedia

    en.wikipedia.org/wiki/Default_route

    In the highest-level segment of a network, administrators generally point the default route for a given host towards the router that has a connection to a network service provider. Therefore, packets with destinations outside the organization's LAN , typically destinations on the Internet or a wide area network , are forwarded to the router ...

  3. IPv6 - Wikipedia

    en.wikipedia.org/wiki/IPv6

    Once a unique link-local address is established, the IPv6 host determines whether the LAN is connected on this link to any router interface that supports IPv6. It does so by sending out an ICMPv6 router solicitation message to the all-routers [44] multicast group with its link-local address as source. If there is no answer after a predetermined ...

  4. Default gateway - Wikipedia

    en.wikipedia.org/wiki/Default_gateway

    If a router finds a match, it will forward the packet through that route; if not, it will send the packet to its own default gateway. Each router encountered on the way will store the packet ID and where it came from so that it can pass the response packet back to the sender. The packet contains source and destination, not all router hops.

  5. IPv6 address - Wikipedia

    Decomposition of an IPv6 address into its binary form. An Internet Protocol version 6 address (IPv6 address) is a numeric label that is used to identify and locate a network interface of a computer or a network node participating in a computer network using IPv6.

    The gateway address (or default gateway) is a router interface connected to the local network that sends packets out of the local network. The gateway has a physical and a logical address. The gateway has a physical and a logical address.

  7. Static routing - Wikipedia

    en.wikipedia.org/wiki/Static_routing

    For instance, a router may have a static or connected route for a local network segment, which is then redistributed over dynamic routing protocols to enable connectivity to that network. [ 4 ] By using the metric to reduce the priority of a static route a fallback can be provided for instance when a DHCP server becomes unavailable.

  8. Dynamic Host Configuration Protocol - Wikipedia

    en.wikipedia.org/wiki/Dynamic_Host_Configuration...

    Many routers and residential gateways have DHCP server capability. Most residential network routers receive a unique IP address within the ISP network. Within a local network, a DHCP server assigns a local IP address to each device. DHCP services exist for networks running Internet Protocol version 4 (IPv4), as well as version 6 .

  9. Multicast address - Wikipedia

    ffx0::/16, ffxf::/16: Reserved ffx1::/16: Interface-local Packets with this destination address may not be sent over any network link, but must remain within the current node; this is the multicast equivalent of the unicast loopback address. ffx2::/16: 224.0.0.0/24: Link-local Packets with this destination address may not be routed anywhere ...
