  2. Subnet - Wikipedia

    en.wikipedia.org/wiki/Subnet

    In IPv6 this is the only standards-based form to denote network or routing prefixes. For example, the IPv4 network 192.0.2.0 with the subnet mask 255.255.255.0 is written as 192.0.2.0 / 24, and the IPv6 notation 2001:db8:: / 32 designates the address 2001:db8:: and its network prefix consisting of the most significant 32 bits.

  3. Classless Inter-Domain Routing - Wikipedia

    A subnet mask encodes the same information as a prefix length but predates the advent of CIDR. In CIDR notation, the prefix bits are always contiguous. Subnet masks were allowed by RFC 950 [6] to specify non-contiguous bits until RFC 4632 [5]: Section 5.1 stated that the mask must be left contiguous. Given this constraint, a subnet mask and ...

    The network address and subnet mask of the interface, along with the interface type and number, are entered into the routing table as a directly connected network. A remote network is a network that can only be reached by sending the packet to another router. Routing table entries to remote networks may be either dynamic or static.

    The network automatically replicates datagrams as needed to reach all the recipients within the scope of the broadcast, which is generally an entire network subnet. Multicast delivers a message to a group of nodes that have expressed interest in receiving the message using a one-to-many-of-many or many-to-many-of-many association; datagrams are ...

    The answer is that it was to augment a decision made during the layout of the LLC header. At the time that the LLC header was being designed, it was thought that a single octet (256 possible values) in the header would be enough to specify all the protocol values that vendors would want to register.
