  2. Wildcard mask - Wikipedia

    en.wikipedia.org/wiki/Wildcard_mask

    A wildcard mask can be thought of as an inverted subnet mask. For example, a subnet mask of 255.255.255.0 (11111111.11111111.11111111.00000000 2) inverts to a wildcard mask of 0.0.0.255 (00000000.00000000.00000000.11111111 2). A wild card mask is a matching rule. [2] The rule for a wildcard mask is: 0 means that the equivalent bit must match

  3. Longest prefix match - Wikipedia

    en.wikipedia.org/wiki/Longest_prefix_match

    In this case, the longest prefix of the candidate routes is 192.168.20.16/28, since its subnet mask (/28) is longer than the other entry's mask (/16), making the route more specific. Forwarding tables often contain a default route , which has the shortest possible prefix match, to fall back on in case matches with all other entries fail.

  4. Mask (computing) - Wikipedia

    en.wikipedia.org/wiki/Mask_(computing)

    To configure IP addresses on interfaces, masks start with 255 and have the large values on the left side: for example, IP address 203.0.113.129 with a 255.255.255.224 mask. Masks for IP ACLs are the reverse: for example, mask 0.0.0.255. This is sometimes called an inverse mask or a wildcard mask. When the value of the mask is broken down into ...

    Casio calculator character sets are a group of character sets used by various Casio calculators and pocket computers. [1] ... ^*1 Back control code. ^*2 Forward ...

  6. Subnet - Wikipedia

    en.wikipedia.org/wiki/Subnet

    The routing prefix of an address is identified by the subnet mask, written in the same form used for IP addresses. For example, the subnet mask for a routing prefix that is composed of the most-significant 24 bits of an IPv4 address is written as 255.255.255.0.

  7. Broadcast address - Wikipedia

    en.wikipedia.org/wiki/Broadcast_address

    As shown in the example below, in order to calculate the directed broadcast address to transmit a packet to an entire IPv4 subnet using the private IP address space 172.16.0.0 / 12, which has the subnet mask 255.240.0.0, the broadcast address is calculated as 172.16.0.0 bitwise ORed with 0.15.255.255 = 172.31.255.255. Directed broadcasts always ...

  8. Routing table - Wikipedia

    en.wikipedia.org/wiki/Routing_table

    network identifier: The destination subnet and netmask; metric: The routing metric of the path through which the packet is to be sent. The route will go in the direction of the gateway with the lowest metric. next hop: The next hop, or gateway, is the address of the next station to which the packet is to be sent on the way to its final destination

  9. TI calculator character sets - Wikipedia

    en.wikipedia.org/wiki/TI_calculator_character_sets

    The TI-86 character encoding aligns with the ASCII printable characters, but includes its own characters in place of the C0 control codes and 0x7F, as well as defining its own characters in the 0x80 to 0xFF range (which is not part of ASCII). [5] [6]
